Answer:
emf = 11.667 V
Explanation:
Given: charge q = 0.060 C, electric potential energy E =0.70 J,
Solution :
by definition 1 volt = 1 joule per coulomb
so Voltage = emf = E/C
emf = 0.70 J / 0.060 C
emf = 11.667 V

Answer:
x = 1,185 m
, t = 4/3 s
, F = - 4 N
Explanation:
For this exercise we use Newton's second law
F = m a = m dv /dt
β - α t = m dv / dt
dv = (β – α t) dt
We integrate
v = β t - ½ α t²
We evaluate between the lower limits v = v₀ for t = 0 and the upper limit v = v for t = t
v-v₀ = β t - ½ α t²
the farthest point of the body is when v = v₀ = 0
0 = β t - ½ α t²
t = 2 β / α
t = 2 4/6
t = 4/3 s
Let's find the distance at this time
v = dx / dt
dx / dt = v₀ + β t - ½ α t2
dx = (v₀ + β t - ½ α t2) dt
We integrate
x = v₀ t + ½ β t - ½ 1/3 α t³
x = v₀ 4/3 + ½ 4 (4/3)² - 1/6 6 (4/3)³
The body comes out of rest
x = 3.5556 - 2.37
x = 1,185 m
The value of force is
F = β - α t
F = 4 - 6 4/3
F = - 4 N
I can interpret this as it's somewhat of all of those, due to the fact that for one thing think of the earth it's a spinning ball of liquid iron, nickel due to one law stating hot liquid metal spinning around creates magnetic fields, ferro magnetic metals are ones such as magnetite which is a natural magnet, it can be found in nature theres a region in the gobi desert that will make a compass needle dance since its surrounded by magnetic rock, ferro magnetic atoms like iron, nickel are great at being and creating magnetic fields due to their ability to change from non magnetic to magnetic quickly and with different ways from inducing as in electromagnetic coils forcing atoms spinning differently to spin the same direction or changing the north south alignment. you can take a iron pipe and hit it with a hammer and after enough wacks the atomic structure will be disrupted and all the atoms line up in tightly compacted lines like grains in wood creating a stronger magnetic pull than if it was just a iron pipe. I hope that helps I like metaphors for understanding those kinds of concepts I hope that's helped.
Answer:
(D)6 times
Explanation:
Hello !
Because when we see the equation of momentum P=mv, where p=momentum
m=mass of the object&
v=velocity of the object
And, p is directly propositional to both mass and velocity.
Thus, p=mv
- p=3m.2v....giving on the values
- p=6(mv)
Therefore, we can conclude by when the mass is tripled and the velocity is doubled the momentum is increased by 6 units.
