Answer:
Explanation:
Answer: Gamma rays
Gamma rays have the highest frequency.
What is an electromagnetic wave?
An electromagnetic wave requires no medium for its propagation.
It consists of a spectrum of different wavelengths.
Different wavelengths of rays have different energies and different frequencies.
Higher frequency rays have the highest energies.
What is gamma-ray?
These are ionized radiations.
Gamma radiations are obtained from the decay of the atomic nucleus.
It has the highest frequency which is why it can penetrate through matter.
It has the smallest wavelength and highest energy.
The frequency of gamma rays is more than 10^19 cycles per second and wavelength less than 100 picometers.
1. What is the force of the marble?
For an object near the surface of the earth, the gravitational force acting upon the object is given by:
F = mg
F is the gravitational force, m is the object's mass, and g is the acceleration of objects due to earth's gravity.
Given values:
m = 0.025kg, g = 9.8m/s²
Plug in the given values and solve for F:
F = 0.025×9.8
F = 0.25N
2. What is the marble's potential energy at the start of its fall?
The gravitational potential energy of an object near the earth's surface is given by:
PE = mgh
PE is the potential energy, m is the object's mass, g is the acceleration of objects due to earth's gravity, and h is the object's relative height.
new given values:
h = 0.08m
Since F = mg, you can simply multiply F×h to get PE. Use the result from question 1:
PE = F×h
PE = 0.25×0.08
PE = 0.02J
Newton's first law is called inertia, or the force an object has to resist unbalanced forces that are placed upon it. The more mass an object has, the more inertia an object has. The less mass an object has, the less inertia an object has.
Answer: A. Radiation can move through empty space to transfer heat; conduction cannot.
Now unlike convection and conduction, radiation does not require matter to transfer heat. It also does not require a medium to transfer heat, crossing off the other options regardless.
I hope this helps!
Magma from the mantle rises and flows out through a vent onto Earth's surface as lava. This molten material, sometimes along with ash, cinders, and rock, builds up a mountain around the vent. The vent and its mountain together are called a sediment.
