The planets in the solar system revolve around the Sun because the Sun is
Answer: Anyway, the basic reason why the planets revolve around, or orbit, the Sun, is that the gravity of the Sun keeps them in their orbits. ... If the Sun weren't there, the Earth would travel in a straight line. But the gravity of the Sun alters its course, causing it to travel around the Sun, in a shape very near to a circle
how does the total mass of each object increases the amount of force that is needed to get them moving at 5 m/s increase by about 200N demonstrate newtons 2nd law
Answer:
The answer is below
Explanation:
Newton's second law of motion states that the force applied to an object is directly proportional to the rate of change of momentum with respect to time, going in the same direction as the force.
Let F = force, m = mass of object, v = velocity of object, mv = momentum.
F = d/dt(mv) = m(dv / dt) = ma; a = acceleration.
Let us assume that the object starts from rest to 5 m/s within 1 seconds, hence:
F = m(dv / dt)
200 N = m[(5 m/s - 0 m/s) / (1 s)]
200 = 5m
m = 40 kg
he distance from Earth to the North Star is about 430 light-years. Which of the following statements describes why scientists use the light-year unit to measure distances in space?
A light-year unit is very small and distances in space are very small.
A light-year unit is very small and distances in space are very large.
A light-year unit is very large and distances in space are very small.
A light-year unit is very large and distances in space are very large.
Answer:
D
Explanation:
because the rest don’t make any sense
A light-year unit is very large and distances in space are very large. Therefore, the correct option is option D.
What is distance?No matter the direction of the journey, distance is the overall path that an item in motion has traveled. Since just the length of the path travelled is calculated as well as the motion's direction is ignored, distance is referred to as a scalar number. The distance can only ever be positive; it can never be 0 or negative.
Displacement generally defined as the overall alteration of an object's location and motion direction. Displacement is recognized as a vector quantity since it takes into consideration both the directions of the motion and the amount of the changing position. Displacement may be zero, positive, or negative. A light-year unit is very large and distances in space are very large.
Therefore, the correct option is option D.

True or false; When Something Heats up, it moves faster, and when something cools down, It moves slower.
Answer:
This is true
Explanation:
Even at the atomic level when an element is heated up, the atoms continue to move faster and continue colliding.
The opposite happens with the cooling of elements.
What effect does this added energy have on the temperature, pressure, and number of collisions?
Answer: Increasing the temperature increases reaction rates because of the disproportionately large increase in the number of high energy collisions. It is only these collisions (possessing at least the activation energy for the reaction) which result in a reaction.

if you need 2.5 moles of of aluminum, how many atoms of aluminum is this?
Answer:
This can be found by my multiplying number of moles with avogadro number
So we have:
2.5 × 6.022 × 10²³
= 15.055 × 10²³
Therefore there are 15.055 × 10²³ atoms in 2.5 moles of Aluminium

What is the momentum of a car with a mass of 1,300 kg traveling north at a speed of 28 m/s?
Answer:
p = 36400 kg·m/s
Explanation:
p=mv
p= Momentum
m= mass (1300 kg)
v= 28
1300 × 28
= 36400 kg·m/s
The Momentum of the car is 36400 kg-m/s.
What is Momentum ?Momentum is the product of the mass and velocity of an object. It is a vector quantity, possessing a magnitude and a direction. m is an object's mass and v is its velocity
Given that,
Mass of the car, m = 1300 kgSpeed of the car, v = 28 m/s (towards north)(m is an object's mass and v is its velocity)
To find :
The momentum of car, p
Solve :
Let p is the momentum of an object. It can be calculated by the product of mass and its velocity. The formula to find it is given by :
p = m x v
= 1300 x 28
= 36400 kg-m/s.
Therefore, the momentum of the car is 36400 kg-m/s.

In general, what causes a sea breeze?
O
A. The difference in density between land and water
B. The difference in cloud cover between land and water
Ο Ο Ο
C. The difference in specific heat capacity between land and water
D. The difference in elevation between land and water
Answer:
The usual cause of sea breeze is the difference in specific heat capacity between land and water Land heats and cools more quickly than water. What is the cause of a sea breeze? The air over the land is warmed and rises, to a greater temperature than that over the sea.
Explanation:
Your answer is C ! <3
The difference in specific heat capacity between land and water is the cause of sea breeze.
What is sea breeze?land and ocean heat up at different rates, sea breezes often occur during hot, summer days. The land surface warms up more quickly than the water surface during the day. As a result, the air above land is warmer than that over water.
Just to refresh your memory, warmer air is lighter than cooler air. Warm air rises as a result. As a result, the warmer air above the ground is rising. The cooler air above the water is moving across the surface of the land to replace the rising heated air as it rises over the land.
This is the sea breeze, which is seen at the top of the next picture. The land breeze that happens is seen at the bottom of the following picture.
Therefore, The difference in specific heat capacity between land and water is the cause of sea breeze.

Answer:
The answer is functioning properly ok dude?
Explanation:
Answer: "The microscopic size of cells enable them to function properly.
Most organisms on Earth are multi-celled." is false
Explanation:
In unicellular organisms, cell division is the means of reproduction; in multicellular organisms, it is the means of tissue growth and maintenance. Survival of the eukaryotes depends upon interactions between many cell types, and it is essential that a balanced distribution of types be maintained. This is achieved by the highly regulated process of cell proliferation. The growth and division of different cell populations are regulated in different ways, but the basic mechanisms are similar throughout multicellular organisms.
