Answer:
The mass of the other block is
Explanation:
From the question we are told that
Mass of the first block is
The height is
The time it takes it is
Generally from kinematic equation
Here u is the initial velocity which zero given that it was at rest initially
So

Answer:
15: Animals are able to detect the first of an earthquake's seismic waves—the P-wave, or pressure wave, that arrives in advance of the S-wave, or secondary, shaking wave. This likely explains why animals have been seen snapping to attention, acting confused or running right before the ground starts to shake.
16: No, it is not even remotely true. Microwaves cook food from the outside in, just like a regular oven. In fact, most of the cooking on the inside of the food, depending on its thickness, is done by heat conduction from the outside surfaces inwards, as the microwaves do not actually penetrate that far into the food.
Answer:
The maximum height is 10.0m
When blue and orange color are given, then : Blue color has shorter wavelength and more energy as compared to orange.
<h3>What is visible spectrum?</h3>
Visible spectrum is that portion of electromagnetic spectrum that is visible to the human eye. Electromagnetic radiation in this range of wavelengths is called visible light and human eye responds to wavelengths from about 380 to about 750 nanometers
Visible light comes in all the colors of the rainbow where each color has its own special frequency and wavelength. When all the colors are together, they make "white" light that we see.
Blue light has shorter wavelength more energy whereas orange light has the longer wavelength and low energy.

Answer:
g= 1.8 m/s²
Explanation:
From conservation of energy we know:
Solving for g with h being the height of the ramp with angle ∅ and length L:
(1)
The velocity v at the bottom of the ramp for a constant acceleration a in a time t is given by:
(2)
Plugging equation 2 in to equation 1:
(3)
