Answer:
D) 15s
Explanation:
let Te be the period of the block-spring system on earth and Tm be the period of the same system on the moon.let g1 be the gravitational acceleration on earth and g2 be the gravitational acceleration on the moon.
the period of a pendulum is given by:
T = 2π√(L/g)
so on earth:
Te = 2π√(L/g1)
= 6s
on the moon;
Tm = 2π√(L/g2)
since g2 = 1/6 g1 then:
Tm = 2π√(L/(1/6×g1))
= √(6)×2π√(L/(g1))
and 2π√(L/(g1)) = Te = 6s
Tm = (√(6))×6 = 14.7s ≈ 15s
Therefore, the period of the block-spring system on the moon is 15s.
As long as you describe the chemical reactions within the torpedo and explain how torpedoes advanced modern warfare.
Archimedes' Principle is a law of physics related to the the ability of an object to float. This is a physical law related to the ability of an object to float that states that any object fully or partially submerged in water and at rest is acted upon in an upward direction, by a force whose magnitude is equal to the weight of the object. Since this force works in the opposite direction, the body/object neither sinks nor rises. If the sunk object displaces as much water as its weight, it does not sink but floats. The best example to explain this law is the ship in the ocean. When the ship enters the ocean, it begins to sink until it has displaced the same amount of ayer which is equal to its own weight, after which it starts to float.
The volume increases. The molecules of that object gain kinetic energy hence colliding more and creating a bigger gap between each other.
Answer:
Explanation:
v = I / (n q A)
where A is the cross sectional area (you are given diameter, so A = (pi/4) * d^2), n is the number of charge carriers in a volume, and q is the charge of each carrier (-1.60x10^-19). I is the current, in Amps.
You will need to either convert your diameter from inches to centimeters or you will need to convert your volume in cc to cubic inches. I'd convert diameter.
