Answer:
The force of the golf ball on Earth!
Explanation:
Action/Reaction Pairs work like this:
Earth on Golfball, Golfball on Earth.
As long as you describe the chemical reactions within the torpedo and explain how torpedoes advanced modern warfare.
Answer:
Forces observed by both is same as both
The frames are non-acceleration
Explanation:
Zweistein = Einstein
=
as tend to zero (0)
< as some quantity is subtracted from the force.
Answer:
a). M = 20.392 kg
b). am = 0.56 (block), aM = 0.28 (bucket)
Explanation:
a). We got N = mg cos θ,
f =
=
If the block is ready to slide,
T = mg sin θ + f
T = mg sin θ + .....(i)
2T = Mg ..........(ii)
Putting (ii) in (i), we get
M = 20.392 kg
b). .............(iii)
Here, l = total string length
Differentiating equation (iii) double time w.r.t t, l, h and h' are constants, so
.....................(iv)
We got, N = mg cos θ
∴
................(v)
Mg - 2T = M
(from equation (iv))
.....................(vi)
Putting (vi) in equation (v),
Using equation (iv), we get,
Answer:
1.8 x 10⁸ N / m²
Explanation:
Volume of 1000 kg of water = 1 m³
Volume of 1000 kg of ice = 1 / .917 = 1.09 m³
Change in volume = .09 m³
Volume strain = Change in volume / original volume = .09 / 1 = .09
Bulk modulus of elasticity of ice is 2 x 10⁹ N / m²
a ) Bulk modulus = change in pressure / volume strain
change in pressure = bulk modulus x volume strain.
Change in pressure = 2 x 10⁹ x .09 = 1.8 x 10⁸ N./ m².
When water inside the cell freezes it creates huge pressure on the cell wall
breaking it . Even walls of many internal structures of cell are broken leading it to die.
