The last is proven
Explanation:
The moon landing is real and if you watch a video with Adam ruins everything then he debunks the theory
(a) The velocity of the first ball before the collision with the second ball is 11.18 m/s.
(b) The final velocity of the two balls after the collision is determined as 5.59 m/s.
<h3>
Speed of the block when pushed by the spring</h3>
The speed of the block when pushed by the spring is calculated as follows;
K.E = Ux
¹/₂mv² = ¹/₂kx²
mv² = kx²
v² = kx²/m
v² = (25 x 0.5²)/0.05
v² = 125
v = 11.18 m/s
<h3>Final velocity of the two balls after the collision</h3>
The velocity of the two balls after the collision is calculated as follows;
Pi = Pf
where;
- Pi is initial momentum
- Pf is final momentum
m1u1 + m2u2 = v(m1 + m2)
0.05(11.18) + 0.05(0) = v(0.05 + 0.05)
0.559 = 0.1v
v = 5.59 m/s

Answer:
Volts/Meter
Newtons/Coulomb
Explanation:
Volts/ Meter and Newtons/Coulomb both are same and the units of Electric field intensity or electric field strength.
Electric field strength E is the force per unit charge. It is measured in Newton/Coulomb in SI unit. It is a vector quantity directed in the direction of force.
Mathematically,
Electric field strength = Force/Charge
E = F / q₀
= Newton / Coulomb = NC⁻¹ 1
We know that
Newton = Joule/meter 2
Also
Volt = Joule/Coulomb 3
So put 3 in 2 we get
Newton = (Volt Coulomb)/meter put in 1
E = (Volt Coulomb)/(meter Coulomb)
= Volt / meter
Hence
Newton / Coulomb = Volt / meter
Impulse in physics is the integral of force, F, with respect with time, t. This value is a vector quantity since force is a vector quantity as well. It can be calculated from the product of force and time. We do as follows:
Impulse = Ft
= m(a)(t)
= m(v/t)t
= 0.046 (42/0.0005) (0.0005)
= 1.932 N-s
