Answer:
Pretty sure it is air mass C
Explanation:
It looks like yhe air has warm air where as the other 2 options have cold air.
according to newton's third law, every action has equal and opposite reaction. in this scenario of making a jump from the boat onto a dock, as i jump my feet in contact with the boat push the boat in backward direction. hence the action force is the push by my feet on the boat. the boat reacts by applying a reaction force on my feet pushing the feet in forward direction. hence reaction force here is the force by the boat on the feet. due to the reaction force of the boat on feet, i am pushed in forward direction to reach the the dock.
Answer:
Rate of heat conduction will be 935 Watt
Explanation:
We have given thickness of the floor d = 1.6 cm = 0.016 m
Area 
Temperature difference 
Thermal conductivity of the wood k = 0.200 w/M-K
We have to find heat conduction
Heat conduction is given by 
Rate of heat conduction will be 935 Watt
Answer:
Speed of the ball in position D 
<u>Explanation:</u>
Given:
Position of B=11.3
Position of D=1.9
Velocity of B=6.2
To Find:
Velocity of D
Solution:
According to the formula, Velocity is given as
=Velocity of B
=Velocity of D
g=acceleration due to gravity=9.8 m/s^2
=Change in position of B and D
Substitute the all values in the above equation we get
![=\sqrt{[38.44+(2 \times 9.8 \times(9.4))]}](https://tex.z-dn.net/?f=%3D%5Csqrt%7B%5B38.44%2B%282%20%5Ctimes%209.8%20%5Ctimes%289.4%29%29%5D%7D)
Result :
The velocity of D is
