What can increase the gravitational potential energy of a object
Answer:
Increase in mass and height
Explanation:
The gravitational potential energy of an object can increase if the mass and height of object is increased.
Gravitational potential energy is the energy due to the position of a body.
It is expressed as:
Gravitational potential energy = mass x acceleration due gravity x height
Increasing mass and height will cause an increase in gravitational potential energy.

Answer:
a
Explanation:
a p ex
The potential energy of the particles increases as intermolecular forces are overcome.
When a substance such as ice melts, its temperature increases. Water molecules become less orderly and they spread apart.
What is potential energy ?"Potential energy is the energy held by an object because of its position relative to other objects, stresses within itself, its electric charge, or other factors." An object can store energy as the result of its position. For example, the heavy ball of a demolition machine is storing energy when it is held at an elevated position. This stored energy of position is referred to as potential energy. Similarly, a drawn bow is able to store energy as the result of its position.

How does convection create wind patterns at a beach? A. The Sun heats the water and the land equally during the day, but at night heat from the land rises, causing warm air over the water to rush toward shore. B. Electromagnetic waves from the Sun are absorbed in Earth's atmosphere, which is warmed and then reemits the heat as electromagnetic waves. C. Increasing temperature means greater kinetic energy, and the kinetic energy shows itself as movement of the air molecules. D. During the day, air over the warm land heats up and rises, while cooler air that was over the water is drawn in to shore to replace it. SUBMIT
Answer:
D. During the day, air over the warm land heats up and rises, while cooler air that was over the water is drawn in to shore to replace it.
Explanation:
Convection creates wind patterns at a beach by the force of land and sea breeze which are different wind patterns that move air masses.
Convection is a form of heat transfer that occur mainly in fluids such as gases and in liquids.
During the day, the air over the land is warmed. The land is a good conductor heat better than the ocean. This air masses rises and move towards the ocean. The colder air from the ocean moves landward to replace this air mass.
As the cold air gets warmer at land, it rises and move ocean-ward again.
Do you think cell division stops after a new baby is born? Why or why not?
Answer:
No.
Explanation:
The method of cell division, the transformation of the baby into an adult in itself is accomplished. Until your death, cell division continues. The formation of new white blood cells to replace the killed ones after a cut and the development of skin to replace the skin that has been cut are some examples of cell division.
A rocket sled accelerates from 10 m/s to 40 m/s in 2 seconds. What is the average acceleration of the sled?
Answer:
15m/s²
Explanation:
Given parameters:
Initial velocity = 10m/s
Final velocity = 40m/s
Time taken = 2s
Unknown:
Average acceleration = ?
Solution:
Acceleration is the rate of change of velocity with time;
Acceleration = [tex]\frac{Final velocity - Initial velocity }{time}[/tex]
Acceleration = [tex]\frac{40 - 10}{2}[/tex] = 15m/s²

A negative charge of - 0.0005 C exerts an attractive force of 9.0 N on a second charge that is 10 m away. What is the magnitude of the second charge?
Answer:
q₂ = 0.0002 C
Explanation:
Given that,
Charge, q₁ = -0.0005 C
The force between two charges, F = 9 N
The distance between charges, d = 10 m
We need to find the magnitude of the second charge. The force acting between two charges is given by :
[tex]F=\dfrac{kq_1q_2}{r^2}\\\\q_2=\dfrac{Fr^2}{kq_1}\\\\q_2=\dfrac{9\times (10)^2}{9\times 10^9\times 0.0005}\\\\q_2=0.0002\ C[/tex]
So, the magnitude of the second charge is 0.0002 C.

A car is traveling east at a speed of 25 m/s. It then takes
5 seconds to a stop at a red light (final velocity=0 m/s).
What is the acceleration of the car?
Answer:
-5m/s²
Explanation:
Given parameters:
Initial velocity = 25m/s
Time = 5s
Final velocity = 0m/s
Unknown:
Acceleration of the car = ?
Solution
The acceleration of a body is the rate of change of the velocity of the body with time.
Acceleration = [tex]\frac{Final velocity - Initial velocity }{time}[/tex]
So;
Acceleration = [tex]\frac{0 - 25}{5}[/tex] = -5m/s²
The car is decelerating at a rate of 5m/s²

Explanation:
A hurdler is 0.635 m from a hurdle when he jumps at 3.22 m/s at a 62.9 degrees angle. How many seconds later does he clear the hurdle? (Hint: it is not necessarily at the highest point in his motion.) (Unit = s) Watch sig figs.
Answer:
Explanation:
The horizontal distance of the hurdle = .635 m
This distance is covered by hurdler by horizontal component of his velocity
horizontal component of hurdler's initial velocity = 3.22 x cos 62.9
= 1.4668 m /s
displacement in horizontal direction = .635 m , acceleration = 0 as no force acts in horizontal direction .
So time taken to clear the hurdle
= .635 / 1.4668 s
= .433 s .

Thermal energy is the sum total of the average kinetic energy within the system.
It is mathematically expressed as:
Quantity of energy = mass x specific heat x change in temperature
We see that the quantity of the thermal energy is directly proportional to mass and temperature changes.

Natural Resources Question 5
Which statement describes an advantage of using renewable
resources?
Select one
-They make energy more affordable
-They will increase the demand for electricity
-They will be available for many years.
-They make electricity less dangerous.
Answer:
-They will be available for many years.
Explanation:
The advantage of using renewable resources is that they will be available for many years.
Renewable resources have very fast turn over time for replenishing, therefore, they are available over an extended period time.
They are not used by consumption and so they will continually be available. This is different from the non-renewable resources which are depleted as they are being used up.
Examples of renewable resources are wind, water and air
The model above shows sunlight that is directly hitting one side of the earth during its winter season. Which sentence explains why this area is experiencing shorter hours of daylight
Answer:
During winter time the northern hemisphere leans away from the sun due to the rotation of earth and due to this change the sunlight is not direct on these areas instead it is spread and due to this the shadows are longer and the sunlight is not intense. The earths rotation around the sun causes the seasons to change and that is why we experience shorter hours of daytime.
