Answer:
Electric dipole
Explanation:
the dipole axis makes an angle with the electric field. depending on direction (clockwise/aniclockwise) you get the torque

The measurement of the wave trough
Well, let’s find the initial velocity first:
Vf = Vi + at
0 = Vi - 9.8*2
0 = Vi - 19.6
Vi = 19.6 m/s
We know the final velocity is 0 because when it hits it’s peak, it’s at 0 m/s.
So now use this kinematic equation to find the final position:
Yf = Yi + Vi*t + 1/2a*t^2
Yf = 0 + 19.6(2) - 4.9(2^2)
Yf = 39.2 - 19.6
Yf = 19.6 meters
If you have any questions for how I derived anything, just lemme know. Most of the info requires thinking and imagining of the situation. I assumed you know gravity is 9.8 and you’re expected to assume velocity is 0 at peak height
<span>The normal force acting on the vehicle is 4440 N. Normal force is the force perpendicular to the ground. The important given values are the mass of the space vehicle (1200 kg) and the gravitational field strength (3.7 N/kg). To get a value of Force in Newtons, we just multiply the two numbers together: force = field strength * mass = 3.7 N/kg * 1200 kg = 4440 N.</span>
<span>We know the change of thermal energy is proportional to the specific heat of the matter, its mass and the change of temperatures, according the following formula:
Q = C*m*(Tf-Ti)
where:
Q is the heat added or removed (in joules, J)
C is the specific heat of the matter, in our case air 1,000 J/(Kg*C)
m is the mass, in our case 50 kg of air
Tf is final temperature
Ti is initial temperature
then:
Q = 1000 * 50 * (30-20) = 500,000 Joules
That means that 500,000 joules need to be added to increase temperature of the room 10 ÂşC (from 20 to 30 ÂşC)</span>
