Explanation: Gravity keeps our bones and bodily muscles from not working, things like dams can be one example of gravitational energy being used for our benefits. Without gravitational energy, our earth most likely won't stay in it's own atmosphere. Another example is like a car on the top of the hill, or a snow pack (Where an avalanche might happen)

Answer:

the correct answer is A

Explanation:

In a series circuit the current flows through the circuit and when it is opened at some point the current stops throughout the circuit.

In a parallel circuit, the current flows through the different branches of the circuit and when the current in one branch is interrupted, it continues to flow through the others.

In this exercises they indicate that the bedroom lights are turned off (the circuit was opened), but the kitchen lights are still on, therefore it is a parallel circuit with at least two branches, the current that circulates through each one depends on the existence on each branch.

Therefore the correct answer is A

Answer:

Long short

Explanation:

1

Dogs that are bigger are selected to be parents.

2

The parents are bred together, and their offspring will be different sizes.

3

The biggest offspring will be selected and bred together.

4

This cycle continues until the dogs have been selectively bred to be bigger than the current world record size.

5

Selective breeders need to ensure that they are not also selecting for disadvantageous traits, like genetic limb defects.

The mass of the ball is 5 kg and it is lifted 10 meters above the ground, its potential energy is 490 Joules.

What is Potential Energy?

Potential energy is the energy that an object possesses due to its position or condition. It is the energy that an object has stored within itself, ready to be converted into other forms of energy.

To calculate the potential energy of an object, we need to know its mass, the acceleration due to gravity, and its height above a reference point. The formula for potential energy is:

Potential Energy = Mass x Gravity x Height

where:

Mass is the mass of the object, in kilograms (kg)

Gravity is the acceleration due to gravity, which is approximately 9.8 m/s^2 on Earth

Height is the height of the object above a reference point, in meters (m)

If the mass of the ball is 5 kg, we can calculate its potential energy if we know its height above a reference point. For example, if the ball is lifted 10 meters above the ground, we can calculate its potential energy as:

Potential Energy = 5 kg x 9.8 m/s^2 x 10 m

Potential Energy = 490 Joules

Answer:

The second ball has four times as much kinetic energy as the first ball.

Explanation:

Kinetic Energy

Is the type of energy an object has due to its state of motion. It's proportional to the square of the speed.

The equation for the kinetic energy is:

[tex]\displaystyle K=\frac{1}{2}mv^2[/tex]

Where:

m = mass of the object

v = speed at which the object moves

The kinetic energy is expressed in Joules (J)

Two tennis balls have the same mass m and are served at speeds v1=30 m/s and v2=60 m/s.

The kinetic energy of the first ball is:

[tex]\displaystyle K_1=\frac{1}{2}m\cdot 30^2[/tex]

[tex]\displaystyle K_1=\frac{1}{2}m\cdot 900[/tex]

[tex]K_1=450m[/tex]

The kinetic energy of the second ball is:

[tex]\displaystyle K_2=\frac{1}{2}m\cdot 60^2[/tex]

[tex]\displaystyle K_2=\frac{1}{2}m\cdot 3600[/tex]

[tex]K_2=1800m[/tex]

Being m the same for both balls, the second ball has more kinetic energy than the first ball.

To find out how much, we find the ratio:

[tex]\displaystyle \frac{K_2}{K_1}=\frac{1800m}{450m}[/tex]

Simplifying:

[tex]\displaystyle \frac{K_2}{K_1}=4[/tex]

The second ball has four times as much kinetic energy as the first ball.

Answer:

he second ball has four X as much kinetic energy as the first ball

Explain:

Kinetic Energy Is the type of energy an object has due to its state of motion. It's proportional to the square of the speed

Answer:

A) v₁ = 5.66 [m/s]

Explanation:

To solve this problem we must use the definition of linear momentum conservation, which tells us that momentum is conservation before and after a collision.

The linear momentum is equal to the mass by the product of the Velocity.

P = m*v

where:

P = lineal momentum [kg*m/s]

m = mass [kg]

v = velocity [m/s]

Now, to the right side of the equal sign will take the linear momentum before the collision and to the left side of the equal sign as after the collision.

Pbefore = Pafter

(m₁*v₁) - (m₂*v₂) = (m₁*v₃) + (m₂*v₄)

where:

m₁ = mass of the car = 1450 [kg]

v₁ = velocity of the car before the collision [m/s]

m₂ = mass of the shopping cart = 60 [kg]

v₂ = velocity of the shopping cart before the collision = -1.2 [m/s]

v₃ = velocity of the car after the collision = 5.13 [m/s]

v₄ = velocity of the shopping cart after the collision = 11.75 [m/s]

Now replacing:

(1450*v₁) - (60*1.2) = (1450*5.13) + (60*11.75)

1450*v₁ - 72 = 7438.5 + 705

1450*v₁  = 7438.5 + 705 + 72

1450*v₁ = 8215.5

v₁ = 5.66 [m/s]

Answer:

Answer:84

Explanation:

To solve this we must be knowing each and every concept related to force. Therefore, 200N is the force that  will be required to accomplish this task.

When applied, force is described as an external source that alters or tends to modify the condition of the body. If indeed the body is moving this should come to rest, but if it is at rest, it will move. It can also induce changes in the body's orientation, form, size, and so on.

One example is pushing or shoving a door with force. Vector quantity, which means it has a magnitude as well as a direction. Newton's second law states that force is defined as the "product of such a body's acceleration and mass.

energy = 3000 Joules

time=10 mins
