O A. 408 J
O B. 7,840,000 J
O C. 2J
O D. 39,200 J
Answers
Answer:
39,200J
Explanation:
just took the test
The meteor's potential energy if it has a mass of 10kg at an altitude of 400 m will be 39200 J
What is potential energy ?Potential Energy that depend upon the relative position of various parts of system . It is an energy possessed by an object by virtue of its position or configuration.
mass(m) = 10kg
g (acceleration due to gravity) = 9.8m/s^2
altitude(height (h)) = 400m
Meteor's Potential energy = m * g * h
= 10 * 9.8 * 400 = 39200 J
correct option will be a) 39200 J

PLEASE HELP!!!!! An electron jumps from one energy level to another in an atom radiating 4.5*10^-19 Joules. If Planck's constant is 6.63*10^-34Js, what is the wavelength of the radiation? (C =3*10^8) 2)
Answers
Answer: λ = 4.42 × 10^-7 metres
Explanation:
The emitting radiation energy is the change in energy dE. Where
dE = 4.5×10^-19J
Planck's constant h = 6.63*10^-34Js,
Speed of light C = 3×10^8
The wavelength(λ) of the radiation can be calculated by using the formula
(λ) = hC/dE
Substitute all the parameters into the formula above
(λ) = (6.63×10^-34 × 3×10^8)/4.5×10^-19
(λ) = 1.989^-25/4.5×10^-19
(λ) = 4.42×10^-7 m
Therefore, the wavelength (λ) of the radiation is 4.42 × 10^-7 metres

HELP WITH THESE TWO PROBS PLEASE
Answers
Answer:
1. She is moving at a speed of \(147.18 ms^{-1}\).
2. The speed of the golf ball is \(78.1 m/s\).
Explanation:
1. We can say , at any moment the skydiver is having a kinetic energy of \(1/2 mv^2\)
(where, \(m\) is her mass and \(v\) is the velocity at that point)
Given, \(1/2mv^2 =704000\)
and, \(m = 65KG\)
So, putting the values we get,
\(v=147.18 ms^{-1}\)
2. \(KE=\frac{1}{2} mv^2\)
\(143.3J =\frac{1}{2} (.047)v^2\)
\(v^2=6097.9 m^2/s^2\)
\(v=78.1 m/s\)
Which of these statements describe friction? Check all that apply. Friction allows objects to slide over each other without any resistance. Friction resists motion. Friction is a force that acts from a distance. Friction is a contact force. Friction is caused by microscopic bumps and ridges on surfaces.
i'll give you a brainlest!
Answers
Answer:
→ Friction resists motion
→ Friction is a contact force.
→ Friction is caused by microscopic bumps and ridges on surfaces.
Explanation:
As the normal force, the friction is a contact force because it result when two objects interact by a direct contact, that is, touching to each other. Friction is important in everyday life and resists motion. For example, the oil in a car engine minimizes friction between moving parts, but a car can move because the friction between the tires and the road, but what about the microscopic level? well, as the normal forces friction forces result from the intermolecular forces between two rough surfaces at points where they come into contact and they are electrical in nature.

Answer:Gravity is the force among the options listed that has not directly changed Earth's surface.
Explanation:
Gravity is a fundamental force that acts on all objects with mass, including the Earth itself, but it does not cause changes or modifications to the Earth's surface features. Instead, gravity influences the movement of materials and the shape of the Earth's surface by exerting a pulling force on objects. On the other hand, folding, erosion, and weathering are all processes that directly contribute to shaping
