Answer:
joule
Explanation:
Let m = mass of the car and v1 = initial velocity and v2 = final velocity
Given.
Initial velocity = 100 km/h
final velocity = 50 km/h
What is work done in the car to slow it from 100km/h to 50km/h?
The work done in the car to slow it from v1 to v2.
w=Δk
joule.
Therefore, the work done is joule
A natural gas power plant focuses on the use of non renewable energy resources.
<h3>What are non renewable energy?</h3>
Non-renewable energy are energy that comes from sources that cannot be exhausted.
- This energy can not be replaced because they don't get exhausted.
- Examples include energy form coal, natural gas, oil.
Therefore, natural gas power plant is an example of non renewable energy source.

There's no way to tell for sure which plant will grow faster, because
we don't know if a plant gets any benefit from red light.
But we do know for sure that it won't be the one we shine green light on.
We know that green light is no use to green plants at all ... that's why
when green light falls on them, they don't even bother absorbing it.
They just let it bounce off, and that's why they look green to us.
Answer:
Iv. The direction of motion of each object is the same.
Explanation:
Momentum of an object is defined as:
where
m is the mass of the object
v is its velocity
Since v is a vector, it follows that p is also a vector, and it has the same direction of the velocity. This means that if two objects have same momentum, then the direction of their momentum vector is also the same: therefore, the direction of motion of each object must be the same.
The other options are wrong, because they just state that only one of the two quantities involved in the equation (mass or velocity) is the same, but the two objects can actually have the same momentum even if they have different masses and velocities (in fact, the only thing that matters is that the product between mass and velocity is the same).
When the moon is waxing it means that the sunlit fraction we can see from earth is getting larger. when it is wanning, the sunlit fraction is getting smaller and even as the phases of the moon change the total amount of sunlight the moon gets remains the same. half the moon is always in sunlight just as half the earth is always in sunlight. but because the period of rotation for the moon is the same as its period of revolution, on earth we always see the same side of the moon. If you lived on the far side of the moon, you would see the sun for half of each lunar day, but you would never see the earth.
