Answer:
v = 2.31 m/s
Explanation:
Kinetic energy will be converted partially into potential energy and rest will remain in the form of kinetic energy .
Initial kinetic energy = 1/2 mu²
u is initial velocity at the bottom .
Potential energy at the top
= mgh
Kinetic energy at the top
= 1/2 m v²
According to conservation of energy
1/2 mu² = mgh + 1/2 m v²
1/2 u² = gh + 1/2 v²
.5 x 4.5² = 9.8 x .76 + .5 v²
10.125 = 7.448 + .5 x v²
v = 2.31 m/s
The magnetic dipole moment of the current loop is 0.025 Am².
The magnetic torque on the loop is 2.5 x 10⁻⁴ Nm.
<h3>What is magnetic dipole moment?</h3>
The magnetic dipole moment of an object, is the measure of the object's tendency to align with a magnetic field.
Mathematically, magnetic dipole moment is given as;
μ = NIA
where;
- N is number of turns of the loop
- A is the area of the loop
- I is the current flowing in the loop
μ = (1) x (25 A) x (0.001 m²)
μ = 0.025 Am²
The magnetic torque on the loop is calculated as follows;
τ = μB
where;
- B is magnetic field strength
B = √(0.002² + 0.006² + 0.008²)
B = 0.01 T
τ = μB
τ = 0.025 Am² x 0.01 T
τ = 2.5 x 10⁻⁴ Nm
Thus, the magnetic dipole moment of the current loop is determined from the current and area of the loop while the magnetic torque on the loop is determined from the magnetic dipole moment.

A prolonged blast (lasting at least 4 seconds) from a vessel in the water is a warning to other vessels in the vicinity that there are vessels in the water that may be difficult to see.
Poor visibility could be due to fog. It is also likely that unseen vessels could appear suddenly around turns or bends, and that it ma not be safe to maneuver without colliding with the unseen vessel.
What should you do when you hear a blast?
a. Reply with a blast of your own to warn other vessels.
b. Slow down in order to better deal with low visibility or coming suddenly upon hidden stationary vessels.
Answer:
0.50
Explanation:
The maximum height is given by here h is the maximum height u is the initial velocity and is the angle of projection
So we can see from the relation that height is universally proportional to the gravity now in question it is given that the planet has the twice the surface gravity than the earth so the height will be half
