Answer:
The magnitude of the change in linear momentum of the ball is 6 kg-m/s.
Explanation:
Given that,
Mass of the ball, m = 1 kg
Initial sped of the ball, u = 3 m/s
It strikes a wall and rebound, moving horizontally to the left at the same velocity of 3 m/s, v = -3 m/s
The magnitude of the change in linear momentum of the ball is given by :
So, the magnitude of the change in linear momentum of the ball is 6 kg-m/s.
Answer:
4m/s
Explanation:
due to newtons second law of motion
the accelerations that result when a 12-N net force is applied to a 3-kg object. A 3-kg object experiences an acceleration of 4 m/s/s.

Changes in the earths ability to reflect sunlight (called the 'albeido') due to clouds and other weather like ice formations set up feedback loops that prevent a perfect equlibrium with the sun.
Answer:
≈ 4.41 x 10^-19
Explanation:
The formula for the energy of light is...
E = hc / λ
where 'h' is Planck's constant: 6.626 x 10^-34 Js
'c' is the speed of light: 2.998 x 10^8 ms
& 'λ' is the wavelength (in this case): 450 nm
1 nanometer (nm) = 1 x 10^-9m
E = (6.626 x 10^-34 Js)(2.998 x 10^8 ms) / (450nm)(1 m / 10^-9 nm)
E ≈ 4.41 x 10^-19 J
I think that's the answer and I hope it helps!
The correct answer would be the first option. Based on the given description above, the type of radiation that is being emitted is ALPHA RADIATION. Alpha radiation is the type of radiation having the lowest penetrative power. Take note that <span>Gamma is stronger than Beta is stronger than Alpha. Hope this answer helps. Have a great day!</span>
