Answer:
6.05 cm
Explanation:
The given equation is
2 aₓ(x-x₀)=( Vₓ²-V₀ₓ²)
The initial head velocity V₀ₓ =11 m/s
The final head velocity Vₓ is 0
The accelerationis given by =1000 m/s²
the stopping distance = x-x₀=?
So we can wind the stopping distance by following formula
2 (-1000)(x-x₀)=[]
x-x₀=6.05* m
=6.05 cm
Answer:
The combined momentum will be 2 units.
Explanation:
Here a piece of putty moving with 2 units of momentum strikes and sticks to a heavy bowling ball that is initially at rest. After the putty sticks to the ball, both are set in motion with a combined momentum. It is a case of inelastic collision in which the momentum of the system remains conserved.
The law of conservation of momentum will be followed here. So, the combined momentum after collision will be same as the initial momentum. Hence, the correct option is (b) "2 units".
Answer:
a)10.08 m/s
b)3.36 m/s
Explanation:
Given that
distance s₁= 160 m
time t₁= 17 s
distance s₂= 80 m
time t₂ = 6.8 s
As we know that
Total distance = Total time x Average speed
s₁ + s₂ = (t₁ + t₂ ) Vavg
Vavg=10.08 m/s
Total displacement = Total time x Average velocity
s₁ - s₂ = (t₁ + t₂ ) Vavg
Vavg=3.36 m/s
a)10.08 m/s
b)3.36 m/s
The SI unit of power is the watt<span>, which is equal to one </span>joule/<span>per second.
So I would say Watt is the answer. Hope it helped. :)

A electron has a negative charge. They represent energy levels.
An example of the use of an electron is the spherical shell. The larger the shell, the more energy the electron has.
