For a wave, the _________ is the distance between two successive crests, while the _________ is the time elapsed between two successive crests passing by the same point.
Answer:
The distance between two successive crests of a wave is one way to define its wavelength, so
λ
=
1.15
m
.
The frequency of a wave is the number of waves passing a given point per second, so
f
=
20
16.2
=
1.23
Hz
.
The speed of a wave is given* as
v
=
λ
f
, so here
v
=
1.15
⋅
1.23
=
1.42
m/s
~~~~
*This is because the wavelength is the "distance per wave" and the frequency is the "number of waves per second," so multiplying the two gives "distance per second." This can be verified with dimensional analysis:
meters
wave
×
waves
second
=
meters

A 1 kg cart has 5 J of work done on it. If the initial velocity of the cart was 3 m/s, what is the final velocity of the cart?
The final velocity of the cart at the given mass is 4.36 m/s.
The given parameters;
mass of the cart, m = 1 kgwork done on the cart, W = 5 Jinitial velocity of the cart, u = 3 m/sThe distance traveled by the cart is calculated as follows;
Fd = W
mgh = W
[tex]h = \frac{W}{mg} \\\\h = \frac{5}{1 \times 9.8} \\\\h = 0.51 \ m[/tex]
The final velocity of the cart is calculated as follows;
[tex]v^2 = u^2 + 2gh\\\\v^2 = (3)^2 + 2(9.8)(0.51)\\\\v^2 = 18.996\\\\v = \sqrt{18.996} \\\\v = 4.36 \ m/s[/tex]
Thus, the final velocity of the cart at the given mass is 4.36 m/s.

1)Calculate the mass of a girl that has a weight of 113 Newtons.
2)Determine the weight of a boy of mass 13.4 Kg.
could someone help e asap with this
Answer:
Explanation:We should know that weight = mass * gravity.
That is weight equals mass times gravity.
Gravity is a force of attraction between any two bodies in the universe. It is directly proportional to product of their masses and inversely proportional to the square of the distance between them.
Gravity is generally measured in terms of acceleration due to gravity, denoted as g. For Earth it is, 9.8 m/s². And for moon, it is about 1.62 m/s².
On Earth, your weight is 70 kg = W
W = mass x 9.8
70 = mass x 9.8
Your mass is 70/ 9.8
i.e approximately 7.14
Weight at the Moon, W' = 7.14 x 1.62
Hence, your weight on the surface of the moon is just 11.56 kg.
Congratulations, you've lost about 58.14 kilograms without any hard exercise. And you're as light as a Sweedish Vallhund! Cheers!

Explain how a carbon atom can move through all four of Earth's spheres. When possible apply
how the compound that carbon is in changed.
Through food chains, the carbon that is in plants moves to the animals that eat them. Animals and plants need to get rid of carbon dioxide gas through a process called respiration. Carbon moves from fossil fuels to the atmosphere when fuels are burned.

A student is moving to college and packs a box so full that they can’t lift it. The student realizes they can push the box across the slick floor to get it to the door. The student applies a force of 40N to the 20 kg. Assume there is negligible friction between the box and the floor.
Calculate the magnitude of the box’s acceleration.
Your answer should have one significant figure.
According to Newton's laws of motion, the acceleration of the box is
proportional to the applied force.
The magnitude of the box's acceleration is 2 m/s²Reasons:
The given parameters are;
Applied force, F = 40 N
Mass of the box, m = 20 kg
Friction on floor surface = Negligible
Solution;
According to Newton's second law of motion, we have;
Force, F = Mass, m × Acceleration, a
Therefore;
[tex]\displaystyle Acceleration, a = \mathbf{\frac{F}{m}}[/tex]
Assuming the force acts in the direction of motion, we have;
[tex]\displaystyle Acceleration \ of \ the \ box, \ a =\frac{40 \, N}{20 \, kg} = \underline{ 2 \, m/s^2}[/tex]

Which of the following best explains what creates this convection current?
options:
The rotation of Earth makes the air above it rotate, but not the same over land and water.
Because of its mass, Earth's gravity creates a high pressure area over both the land and water.
Salt in the ocean makes it more dense than the land, so its gravity pulls more on the air above it.
During the evening, the land cools off more quickly than the water. The cooler land cools the air above it, while the warmer water warms the air above it. These differences in air temperature create the convection.
Answer:
During the evening, the land cools off more quickly than the water. The cooler land cools the air above it, while the warmer water warms the air above it. These differences in air temperature create the convection.

A room has a volume of 160 m3. An air-conditioning system is to replace the air in this room every 21.3 minutes, using ducts that have a square cross section. Assuming that air can be treated as an incompressible fluid, find the length of a side of the square if the air speed within the ducts is (a) 3.00 m/s and (b) 6.00 m/s.
Answer:
A. 0.204203928 m
b. 0.1443939822
Explanation:
Givens:
Volume (V) = 160 m^3
velocity 1 (v1) = 3.00 m/s
velocity 2 (v2) = 6.00 m/s
Time (t) = 21.3 minutes = 1278 seconds
Side length = ?
V = A*v*t
A = s^2
V = s^2*v*t
s= [tex]\sqrt{\frac{V}{v*t} }[/tex]
A.
s = [tex]\sqrt{\frac{V}{v*t} }[/tex] = [tex]\sqrt{\frac{160}{3.00*1278} }[/tex] = 0.204203928 m
B.
s = [tex]\sqrt{\frac{V}{v*t} }[/tex] = [tex]\sqrt{\frac{160}{6.00*1278} }[/tex] = 0.1443939822 m

It requires 25 N of force to move a 90 kg box 120 meters across a warehouse floor, then lift it 0.5 meter to put it in a truck. Calculate the total work done to load
this box.
Answer:
Horizontal Work done + vertical work done
Explanation:
1.) First calculate the work done to move box in horizontal direction:
W = Fs
= 25N × 120m
= 3000 Joules
2.) Work done against gravity in vertical direction:
Ep = mgh
= 90x10x.0.5
= 450 Joules
Total Work done = 3000 + 450 = 3450 Joules
