Answer:
Explanation:
The magnetic force between two current-carrying wires is given by:
where
is the vacuum permeability
I1 and I2 are the two currents
r is the distance between the wires
Here we have:
Substituting into the equation,
The ultimate source of energies for fossil fuels, solar cells and windmills is the solar energy.
The sun is the ultimate source of energy for our planet. It is an alternative energy resource that cause no pollution and is <span>environment friendly. </span>
Answer:
a. There is a force on Jupiter toward the center of the orbit.
d. Jupiter is accelerating toward the center of the orbit.
Explanation:
Let us look at each of the choices one by one:
a. There is a force on Jupiter toward the center of the orbit.
True. The sun being at the center of Jupiter's orbit, pulls the planet towards it (providing the centripetal force), therefore, there exists a force on Jupiter toward the center of the orbit.
b. There is a force on Jupiter pulling it out from the center of the orbit.
Nope. The centripetal force due to gravity acts towards the center of the orbit.
c. There is a force on Jupiter in the direction of its motion.
Nope. There exists only the centripetal force acting towards the center of the orbit,
d. Jupiter is accelerating toward the center of the orbit.
Yes. Because of the centripetal force gravity provides, Jupiter is accelerating towards the center of the orbit, but it does not fall in because it has velocity perpendicular to the direction of its acceleration.
Answer:
Uh, I could be wrong but doesn’t it mean that the wave and particle are reacting together to make light? I think it’s something like that... I hope this helps!
Answer:
Answer:
77.58°
Explanation:
Let the projectile is projected at an angle θ and the velocity of projection is u.
At the maximum height, the projectile has only horizontal component of velocity.
Let the velocity at maximum height is v.
According to the question, the velocity at maximum height is 21.5% of initial velocity.
v = 21.5 % of u
u Cos θ = 21.5 % of u
u Cos θ = 0.215 u
Cos θ = 0.215
θ = 77.58°
Thus, the angle of projection is 77.58°.
