Answer:

A rock dropped from the ceiling of a truck's cargo bay, with the truck moving at constant velocity, the rock strikes the floor exactly below the midpoint of the ceiling.

Explanation:

An object moving at a constant velocity, is changing its displacement at an equal time.That is, the object is moving on a straight line at a constant speed.

Also an object with a constant velocity is not accelerating, since acceleration is the change in velocity with respect to time.

Therefore, A rock dropped from the ceiling of a truck's cargo bay, with the truck moving at constant velocity, the rock strikes the floor exactly below the midpoint of the ceiling.

A small electronic device is rated at 0.16 W when connected to 115 V. What is the resistance of this device?
Ierofanga [76]

Answer:

150156.25 Ω

Explanation:

Resistance: This can be defined as the opposition to the flow of electric current in a circuit. The S.I unit of resistance is Ohm's (Ω)

The expression for resistance is given as

P = V²/R................ equation 1

Where P = power, V = Voltage, R = Resistance.

Making R the subject of the equation,

R = V²/P.................. Equation 2

Given: V = 115 V , P = 0.16 W.

Substitute into equation 2

R = 155²/0.16

R = 150156.25 Ω

Hence,

The resistance = 150156.25 Ω

According to Coulomb’s Law, the force between two charged objects is related to _____.
Natasha_Volkova [10]

Answer:

A.) the inverse of the square of the distance separating them

Explanation:

Coulombs law states that "the force of attraction between two charges is directly proportional to the product of the charges and inversely proportional to the square of the distance between them."

Mathematically, F = kq1q2/r²

Where q1 and q2 are the charges

r is the distance between the charges.

According to the law, the force between two charged objects is related to the inverse of the square of the distance separating them.

Calculate the weight of an apple of mass 100grams on Earth
11111nata11111 [884]

Answer:

In physics the standard unit of weight is Newton, and the standard unit of mass is the kilogram. On Earth, a 1 kg object weighs 9.8 N, so to find the weight of an object in N simply multiply the mass by 9.8 N. Or, to find the mass in kg, divide the weight by 9.8 N.
