Two cars collide in a parking lot. Before the collision, their total momentum was 1800 kg m/s to the east. What is their total m

omentum after the collision.

During collision there is no force on two cars together

So here we can say

F = \frac{\Delta P}{\Delta t}

Since force on the system is zero

0 = \frac{\Delta P}{\Delta t}

\Delta P= 0

P_i = P_f

So after collision momentum will remain the same i.e. 1800 kg m/s

Light is shone on a diffraction grating
Pani-rosa [81]

Answer:

    λ = 482.05 nm

Explanation:

The diffraction phenomenon and the diffraction grating is described by the expression

         d sin θ = m λ

where d is the distance between two consecutive slits, λ the wavelength and m an integer representing the order of diffraction

in this case they indicate the distance between slits, the angle and the order of diffraction

         λ = \frac{d sin \theta }{m}d sin θ / m

let's calculate

         λ = 1.00 10⁻⁶ sin 74.6 / 2

         λ = 4.82048 10⁻⁷ m

Let's reduce to nm

         λ = 4.82048 10⁻⁷ m (10⁹ nm / 1 m)

         λ = 482.05 nm

What is the mass of a 735-N weight on Earth?
Allisa [31]
W = mg,      Assuming g ≈ 9.8 m/s² on the earth surface.

735 N =  m* 9.8

735/9.8 =  m

75 = m

Mass , m = 75 kg.  B.

Please help!How is constant or uniform acceleration used to explain free fall?
garik1379 [7]
Free fall is a special case of motion with constant acceleration, because acceleration due to gravity is always constant and downward. For example, when a ball is thrown up in the air, the ball's velocity is initially upward.
