Answer:
zero
Explanation:
Acceleration is a measure of the rate of change of velocity. If the velocity is unchanging, its rate of change is zero.
The acceleration is zero.
Its acceleration will be 0.825 m/s²
What is Acceleration ?
Acceleration is the rate of change of velocity. It is measured in m/s²
Given that a car is driving 8.5 m/s, and speeds up to 11.8 m/s over a period of 4 seconds.
The parameters to consider are;
- Initial velocity u = 8.5 m/s
- Final velocity v = 11.8 m/s
a = Δv ÷ t
a = (v - u) / t
a = (11.8 - 8.5) / 4
a = 3.3 / 4
a = 0.825 m/s²
Therefore, its acceleration will be 0.825 m/s²

We can't tell from the information in the question.
Weight = (mass) x (acceleration of gravity).
In order to find any of those quantities, we need to know
the other TWO things.
We can't answer the question until we know either the mass
of the book, or its weight on some other planet other than Venus.
Answer and Explanation:
Before turning a hot plate on, one should consider these points:
- Check for the leads and ensure they does not trail in liquid.
- The cable should be checked for any exposed wire before turning on in order to prevent any shock.
- Any oil residue should be wiped off of the hot plate to ensure its longevity.
- It should be placed in a stable place in order to ensure safety against any hazard.
- Thus all the above mentioned points are correct to ensure safety.
Answer:
The speed of galaxy relative to the earth is
Explanation:
Given :
Observed frequency
Actual frequency
For finding the speed of galaxy relative to the earth.
From the doppler effect of light,
Where , relative speed
Therefore, the speed of galaxy relative to the earth is
