(a) The average velocity of the car in m/s for the first leg of the run is 36.2 m/s.
(b) The average velocity (in m/s) for the total trip is 0.
<h3>
Average velocity </h3>
The average velocity of the car in m/s for the first leg of the run is calculated as follows;
Average velocity = total displacement/total time
Average velocity = (760) / (21) = 36.2 M/S
<h3>
Average velocity for total trip</h3>
The average velocity (in m/s) for the total trip is calculated as follows;
v = total displacement/total time
v = 0/(26 + 21)
v = 0
Thus, the average velocity of the car in m/s for the first leg of the run is 36.2 m/s.
The average velocity (in m/s) for the total trip is 0.

gravitational force between two objects is given as
F = G m₁ m₂/r²
where m₁ = mass of first object , m₂ = mass of second object , r = distance between the two objects .
Initial case :
m₁ = m₂ = m
gravitational force between the objects is given as
F = G m²/r²
Final Case :
m₁ = m₂ = 3 m
new gravitational force between the objects is given as
F' = G (3m)²/r²
F' = 9 G m²/r²
F' = 9 F
hence the gravitational force between the two objects becomes 9 times.
Answer:
Explanation:
Given:
- mass of steam,
- temperature of steam,
- temperature of resultant water,
We have,
- latent heat of vapourization of water,
- specific heat capacity of water,
<em>When we cool the steam of 100°C then firstly it loses its latent heat to convert into water of 100°C and the further cools the water.</em>
<u>Now the heat removed from steam to achieve the final state of water:</u>
Answer:
Explanation:
As we know the , equation of time period for simple pendulum ,
T = 2*pi*
hence putting values we get ,
the solution is in picture ,
