Explanation:

Jared would describe a square as having four equal sides and four right angles. This is Jared’s conceps of a square.

A square has four equal sides, four vertices, and is a closed, two-dimensional object. It has parallel sides on either side. A square is also equivalent to a rectangle with equal length and width.

Many objects can be found in your surroundings that have a square shape. The chessboard, craft sheets, bread slice, picture frame, pizza box, wall clock, etc. are typical instances of this shape.

A square is a two-dimensional closed shape with 4 equal sides and 4 vertices. Its opposite sides are parallel to each other. We can also think of a square as a rectangle with equal length and breadth.

Therefore, Jared would describe a square as having four equal sides and four right angles. This is Jared’s conceps of a square.

B. racism and its adverse effects on child development

Explanation:

Dr. Mamie Clark studied the effects of segregation and racism on the self-esteem of black children.

According to Clark in O'Connell & Russo, 2001, p. 271; "To separate them from others of similar age and qualifications solely because of their race generates a feeling of inferiority as to their status in the community that may affect their hearts and minds in a way unlikely ever to be undone...."

One of her works titled "The Development of Consciousness of Self and the Emergence of Racial Identification in Negro Preschool Children" investigated the early level of conscious racial identity in black preschool children.

Answer:

See the answer below

Explanation:

This is because, at 20 °C, the solution has become saturated with the baking soda.

The solubility of a substance is the maximum amount of that substance that will dissolve in a particular solvent at a given temperature. The solubility of a substance generally increases with an increase in temperature.

At 20 °C temperature, the maximum amount of baking soda that can dissolve in a liter of water has been exceeded by Miguel. Hence, no matter how hard he tries to stir the solution, the excess baking soda will not dissolve.

The reason he can’t get all of the baking soda to dissolve is; because at 20 °C, the solution has become saturated with the baking soda.

For us to say a substance is soluble, it means that the maximum amount of that substance will dissolve in a particular solvent at a given temperature. Thus, the solubility of a substance is said increase with a corresponding increase in temperature.

From the question, at 20 °C temperature, miguel has exceeded the maximum amount of baking soda that can dissolve in a liter of water. Therefore, no matter how hard he tries to stir the solution, it will not dissolve due to the excess soda.

2nd one :)

Explanation:

Answer:  the second one

Explanation:

Answer:

the pressure will increase.this will cause the molecules of the gas will move faster and thats why the pressure or force increase the volume is the same

Answer:

(a). The relative humidity is 20.57%

(b). The dew point is 79.114°F

(c). It take for the air to reach saturation is 17 hours.

(d). The water is 7.6g/kg.

Explanation:

Given that,

Temperature = 35°

Mixing ratio = 7.6 g/kg

(a). We need to calculate the relative humidity

Using formula of relative humidity

[tex]relative humidity=\dfrac{mixing\ ratio}{36}\times100[/tex]

[tex]relative humidity=\dfrac{7.6}{36.94}\times100[/tex]

[tex]relative humidity=20.57\%[/tex]

(b). We need to calculate the dew point

Using formula of dew point

[tex]dew\ point=T^{\circ}F-\dfrac{(100-relative\ humidity)}{5}[/tex]

Put the value into the formula

[tex]dew\ point=95-\dfrac{100-20.57}{5}[/tex]

[tex]dew\ point=79.114^{\circ}F[/tex]

(c). If the room temperature decreases by 5°C per hour

We need to calculate the time

Using formula of time

[tex]t=\dfrac{T_{a}-increase\ temperature}{5}[/tex]

Put the value into the formula

[tex]t=\dfrac{95-10}{5}[/tex]

[tex]t=17\ hours[/tex]

(d). If the temperature of the room continues to decrease for one more hour,

We need to calculate the how many grams of water vapor

Using given data

The water of 7.6g/kg vapour will have to condense out of air for the maintain relative humidity at 100%

Hence, (a). The relative humidity is 20.57%

(b). The dew point is 79.114°F

(c). It take for the air to reach saturation is 17 hours.

(d). The water is 7.6g/kg.

Answer:

temp: 35° c (95°f)

MR:7.6

SMR: 36.5

RH: 21% (20.82)

Dew Point: 10° C 

5°c per hour: 5 hours for the 35°c air temp to reach the 10°c dew point

1 more hour: Temperature will decrease to 5°c, half the water molecules dewpoint "size" I view it as, and 3.8g/kg of water vapour has condensed out

so

1. 21%

2. 10° C 

3. 5 hours

4. 3.8g/kg

Answer:

The astronaut's mass is 16 kg.

Explanation:

Mass can be defined as a measure of the amount of matter an object or a body comprises of. The standard unit of measurement of the mass of an object or a body is kilograms.

Irrespective of the location of an object or a body at a given moment in time, the mass (amount of matter that they're made up of) is constant. This ultimately implies that, whether you're in the moon, space, earth or any other place, your mass remains the same (constant).

Therefore, if an astronaut has a mass of 16 Kg on Earth, his mass on the moon and on the space station would remain the same, as his original mass of 16 Kg because mass is indestructible.

Answer:

9.8 m/s/s

Explanation:

As such, all objects free fall at the same rate regardless of their mass. Because the 9.8 N/kg gravitational field at Earth's surface causes a 9.8 m/s/s acceleration of any object placed there, we often call this ratio the acceleration of gravity

Based on the scenario in the question, it should be noted that leather shoes offer more protection than canvas shoes and that steel toed boots are essential to protecting your feet from injury.

Leather shoes are more durable and offer better protection than canvas. The strength of the material that they're made from can help in offering extra protection which is necessary in an environment where there's possibility of accidents involving falling objects.

Also, for the people who work in a work environment with many heavy machines and equipments, it is vital to it on protective steel toed boots in order to prevent the workers from feet related injuries.

Answer:

The length of the driveway is 4.98 m

Explanation:

Given that m = mass of car = 2.1 × 10³ kg, d = length of driveway,  f = frictional force = 4.0 × 10³ N, v = velocity of car at bottom of driveway = 3.8 m/s, u = speed of car at top of driveway = 0 m/s (since it starts at rest) and θ = slope of driveway = 20°

The component of the weight of the car along the driveway  minus the frictional force = the net force. So,

mgsinθ - f = ma where a = acceleration of the car

a = gsinθ - f/m

substituting the variables, we have

a = 9.8 m/s²sin20° - 4.0 × 10³ N/2.1 × 10³ kg

a = 3.352 m/s² - 1.905 m/s²

a = 1.447 m/s²

a ≅ 1.45 m/s²

Using v² = u² + 2ad, we find the length of the driveway, d. So,

d = (v² - u²)/2a

Substituting the values of the variables, we have

d = (v² - u²)/2a

d = ((3.8 m/s)² - (0 m/s)²)/(2 × 1.45 m/s²)

d = 14.44 m²/s² ÷ 2.9 m/s²

d = 4.98 m

So, the length of the driveway is 4.98 m

The length of the driveway on which the car is moving is 5 m.

The given parameters;

The net horizontal force on the car is calculated as follows;

[tex]mgsin \theta - F = ma\\\\a = \frac{mgsin \theta - F}{m} \\\\a = \frac{(2100 \times 9.8 \times sin \ 20) - 4000}{2100}\\\\a = 1.45 \ m/s^2[/tex]

The length of the driveway is calculated as follows;

[tex]v^2 = u^2 + 2as\\\\s = \frac{v^2 - u^2 }{2a} \\\\s = \frac{3.8^2 - 0}{2\times 1.45} \\\\s = 5 \ m[/tex]

Explanation:

Answer:

Although glucose can be more concentrated outside of a cell, it cannot cross the lipid bilayer via simple diffusion because it is both large and polar. To resolve this, a specialized carrier protein called theglucose transporter will transferglucose molecules into the cell to facilitate its inward diffusion.

a) Velocity is a vector quantity

e) Velocity is a speed with direction

=================================================

Explanation:

If we know the velocity of an object, then we know how fast it's going (speed) and where it's going (direction). It is a vector because the direction of the vector determines the direction, and the length of the vector (aka magnitude) determines the speed. So in a sense we've built in two facts of data into one visual.

An example of velocity: 10 miles per hour north. Here we have the speed of 10 mph and the direction north.

Extra info:

a. Velocity is a vector quantity.

b.Velocity is a scalar quantity.  NOT

c. Velocity is the same thing as speed. NOT

d.Velocity is speed with net force.  NOT

e. Velocity is speed with direction.
