An insulator does not have electrons that are free to move, and a conductor does.
Answer:
0.392
Explanation:
Mm = 0.11Me
Rm = 0.53Re
g = GM / r^2
G = 6.67 * 10^-11
gmars = (G * 0.11Me) / (0.53Re)^2
Recall:
gearth = GMe /Re^2
Hence, gmars in terms of gearth equals
gmars = gearth * (0.11 / 0.53^2)
gmars = gearth * 0.3915984
gmars = 0.392gearth

Explanation:
Force is simply a push or a pull exerted by one object on another. For an example, when a muscle contracts it creates a force that is transferred to the tendon to pull on the bony attachment, thus resulting in motion.
Answer:
<em>The rock reaches a maximum height of 442.225 m and was thrown at a speed of 93.1 m/s</em>
Explanation:
<u>Vertical Launch</u>
The rock is launched up with a certain speed vo, it reaches its highest point at a height h when the speed is zero, and then it stars a free-fall motion until it hits the ground at time t.
The maximum height is given by
The rock takes the same time to reach this point as to return to the ground, thus we can calculate the maximum height
The rock was thrown up at a speed
Answer:
Explanation:
given,
Area of rectangular loop = 0.15 m²
Magnetic field = B = 0.20 T
angle between magnetic field and the normal to the plane = π/2
increasing at the rate = 0.60 rad/s
magnitude of emf induced = ?
induce emf through the loop
Φ = BA cos θ
now substituting all the given values
the magnitude of induced emf is equal to
