Answer:
where L is the length of the ramp
Explanation:
Let L (m) be the length of the ramp, and g = 9.81 m/s2 be the gravitational acceleration acting downward. This g vector can be split into 2 components: parallel and perpendicular to the ramp.
The parallel component would have a magnitude of

We can use the following equation of motion to find out the final velocity of the book after sliding L m:

where v m/s is the final velocity,
= 0m/s is the initial velocity when it starts from rest, a = 2.87 m/s2 is the acceleration, and
is the distance traveled:


The answer will be pressure.
Pressure is force per unit area.
Answer:
Sound will travel the slowest in Air
Explanation:
The higher the m/s is, the faster the sound travels
Answer:
Gravitational lensing is how we know there is dark matter
What this means is that the light is bending as the light travels from the source to the observer, and if there are any 'holes' in between the beam, that is where 'dark matter' exists
Explanation:
A testing instrument that's used to measure electrical signals
in a circuit and display them as waveforms on a screen is called
an oscilloscope.
