Answer: 3,383.5 kg
Explanation:
from the question we were given the following
tension (T) = 4.5 x 10^4 N
maximum acceleration (a) = 3.5 m/s^2
acceleration due to gravity (g) = 9.8 m/s^2 ( it's a constant value )
mass of the car and its contents (m) = ?
we can get the mass of the car and it's contents from the formula for tension which is T = ma + mg
T = m (a + g)
therefore m = T / (a+g)
m = (4.5 x 10^4 / ( 3.5 + 9.8 )
m = 3,383.5 kg
Answer:
Image B
Explanation:
although I'm not exactly sure, i've recently gotten this question as well. but model B demonstrates the force- distance trade off because you can see how in that image them distance is increased in the force is decreased with the object being shorter. hopefully this helps in some way
Answer: The penetrating power of alpha rays, beta rays, and gamma rays varies greatly. Alpha particles can be blocked by a few pieces of paper. Beta particles pass through paper and Gamma rays are the most difficult to stop and require concrete, lead, or other heavy shielding to block them.
Answer:
The Kinetic Theory of Matter or KTM as i will call it, states that every object is made of many many small particles (humans are made of sextillions of atoms), and that they are constantly moving and bumping each other. The degree to which the particles move is determined by the amount of energy they have and their relationship to other particles.
An example would be Brownian Motion- the random movement of dust particles because of collisions with "air" molecules and how gases behave i.e. Boyle's, Charles', and Gay-Lussac's Laws.
