Answer:
2.461
Explanation:
Let mass of Bonzo = m1
Mass of Ender =m2
When they push eachother from stationary position
Initial velocity of Bonzo = Vib=0 m/s
Final velocity of Bonzo = Vfb= 1.3 m/s
Initial velocity of Ender = Vie= 0 m/s
Final velocity of Ender = Vfe= -3.1 m/s
We know initial momentum = final momentum
==> m1Vib+m2Vie = m1Vfb+m2Vfe
==> 0+0= m1×1.3 +m2×(-3.1)
==> 1.3m1-3.1m2=0
==> 1.3 m1 = 3.2 m2
==> m1/m2 = 3.2/1.3
==> m1/m2 = 2.461
Answer:
The displacement of the car after 6s is 43.2 m
Explanation:
Given;
velocity of the car, v = 12 m/s
acceleration of the car, a = -1.6 m/s² (backward acceleration)
time of motion, t = 6 s
The displacement of the car after 6s is given by the following kinematic equation;
d = ut + ¹/₂at²
d = (12 x 6) + ¹/₂(-1.6)(6)²
d = 72 - 28.8
d = 43.2 m
Therefore, the displacement of the car after 6s is 43.2 m

Answer:
Explanation:
When a person shouts it emits 1 W of energy as sound waves, P = 1 W
Let I is the sound intensity 1 meters from such a person. We know that the power per unit area is called the sound intensity of the person. Its formula is given by :
So, the sound intensity of such a person is 
. Hence, this is the required solution.
There are no appropriate units for power on the list you provided
