P=4800kgm/s
As
p=mΔv
where p is momentum, m is mass and v is velocity
Given values is
m =1200kg
Δv= 17m/s-13m/s=4m/s
Now
p=mΔv
p=(1200kg)*(4m/s)
p=4800kgm/s
You are looking at yourself in a plane mirror, a distance of 3 meters from the mirror. your brain interprets what you are seeing in the mirror as being a person standing 6 meters from you.
<h3>Calculation</h3>
The plane mirror shows an exact replica of the real world. that means the distance of you from the mirror is the same distance as your reflection form the mirror at the opposite side of the mirror.
Thus, distance of image from the plane mirror is same as the distance of object (person) from the plane mirror but the image is formed behind the mirror.
Thereby we have v=u=3 m
Thus, distance between image and the person
is d = v + u = 3 + 3 = 6 m
Thus, the person is 6 meters away from the image.

We know, I = Q / t
Here, Q = 150 C
t = 30 s
Substitute their values,
I = 150 / 30
I = 5 A
In short, Your Answer would be 5 Ampere
Hope this helps!
Answer:
F = 400 N
Explanation:
Given,
The acceleration of the car, a = 8 m/s²
The mass of the passenger, m = 50 Kg
The force acting on a body is equal to the product of the mass and its acceleration
F = m x a newtons
Substituting the given values in the above equation,
F = 50 Kg x 8 m/s²
= 400 N
Hence, the force exerted by the person on the seat belt is, F = 400 N
The radiation of the solar rays of the sun can damage and heat up land closer but at the same time cool because of the atmosphere
