Suppose that you connect the terminals of two batteries of different emfs positive to positive and negative to negative (opposin

g each other) in a circuit. If you wanted to add in a capacitor to charge it from the batteries, would you be able to get more charge onto the capacitor or less charge, than if there was only one battery. (hint: start this problem by aligning the batteries positive to negative, and think of it from conservation of energy perspective).

Answer:

Answer is explained in the explanation section below.

Explanation:

This question is very basic and easy. The answer to this question is:

Answer: If both batteries are connected we would get less amount of charge as compared to connected a single battery.

Reasoning:

If both batteries are connected in a manner of positive terminal to positive terminal and negative terminal to negative terminal then a capacitor is added to charge it from the batteries then, total electromotive force (emf) would decrease.

As a result, the capacitor added would get less amount of charge stored. But capacitor added will get more amount of charge stored when a single battery is connected.

A 0.060-kg ice hockey puck comes toward a player with a high speed. The player hits it directly back softly with an average forc
kramer

Answer:u=-22 m/s

Explanation:

Given

mass of puck m=0.06\ kg

Average force f_{avg}=1.5\times 10^3\ N

time of contact t=1.2ms=1.2\times 10^{-3}\ s

puck leaves with a velocity of v=8\ m/s

We know impulse is F_{avg}\Delta t=\text{change in momentum}

therefore

1.5\times 10^3\times (1.2\times 10^{-3})=P_f-P_i

P_i=0.06\times 8-1.8

P_i=0.48-1.8=-1.32\ kg-m/s

Final momentum P_f=m\times v_f

P_f=0.06\times 8

P_f=0.48\ kg-m/s

Impulse on the ball =F_{avg}\Delta t

Impulse=1.5\times 10^3\times 1.2\times 10^{-3}=1.8\ N-s

Initial velocity is given by

u=\frac{P_i}{m}=\frac{-1.32}{0.06}

u=-22\ m/s

i.e. initially ball is moving towards -x-axis

Explain the energy transfer if a book on the edge of a table, falls to the floor. There should be 3 types of energy transfers.
gavmur [86]

Answer:

potential energy

kinetic energy

thermal energy

Explanation:

The book's potential energy can be released by knocking it off the table. As the book falls, its potential energy is converted to kinetic energy. When the book hits the floor this kinetic energy is converted into heat and sound by the impact.

A 59.31 kg rock is sitting at the top of a cliff that is 300 m tall. What is the gravitational potential energy of that rock?
Diano4ka-milaya [45]

Answer:

The gravitational potential energy of that rock is 174371.4 J.

Explanation:

Given

  • Mass m = 59.31 kg
  • Height h = 300 m

To determine

We need to find the gravitational potential energy of the rock

We know that the potential energy of a body is termed as the stored energy due to its position.

One kind of energy comes from Earth's gravity — Gravitational potential energy (GPE).

Gravitational potential energy (GPE) can be determined using the formula

GPE = mgh

where

  • m is the mass
  • g is the gravitational acceleration which is equal to g = 9.8 m/s²
  • h is the height
  • GPE is the Gravitational potential energy

now substituting m = 59.31, h = 300 and g = 9.8

GPE = mgh

         =59.31\times 9.8\times 300

         =174371.4 J

Therefore, the gravitational potential energy of that rock is 174371.4 J.

What is force? In physics class eleven​
spayn [35]

Answer:

Explanation:

In Physics, force is defined as: The push or pull on an object with mass that causes it to change its velocity. Force is an external agent capable of changing the state of rest or motion of a particular body. It has a magnitude and a directionForce is an external agent capable of changing the state of rest or motion of a particular body. It has a magnitude and a direction. The direction towards which the force is applied is known as the direction of the force and the application of force is the point where force is applied.

The Force can be measured using a spring balance. The SI unit of force is Newton(N).
