Given:
Time: 3.5 hrs
Velocity: 120 miles/hr
Now Distance= Speed × Time
Now Velocity and speed have the same magnitude. Velocity being a vector quantity has a definite direction. Whereas speed is a scalar quantity,it indicates only the magnitude an doesn't define any direction.
Hence Distance = Velocity x time
Distance = 3.5 × 120 = 420 miles
The correct answer to the question above is hypertonic. When celery is being placed in a glass of pure water, the solution inside its cells is going to appear as hypertonic compared to the water. This means that the cells inside has a higher concentration than outside.
In fresh water sound waves travel at 1497m/s at 25 degrees, I'll assume that's the characteristics of the water.
If it's 0.01s then you need to divide the speed by 100 to get the, 14.97, however it gets there and back in that time so you need to halve it.
<u>7.485m</u>
the answer is True you can convert matter and energy
Answer:
<h2>Total thermal energy for all air molecules is 59.54 J</h2>
Explanation:
As we know that the ball comes to rest finally so here we can say that
initial total potential energy of the ball is transferred to the air molecules
So here we have
So here we have
So all the gravitational potential energy of the ball will convert into thermal energy of air molecules which is equal to 59.54 J
