marusya05 [52]

If you want to maximize your potential energy, you can move the cart in any direction and get the same outcome because the distance it travels in each direction is equal.

The energy that a body possesses in its resting state is called its potential energy. The energy of a moving object is known as its kinetic energy. Stored energy that is conditional on the spatial orientation of the system's components; is also known as potential energy.

When a spring is either squeezed or stretched, the resulting increase in potential energy can be used to do work. Potentially, a steel ball has more energy in the air than it does when it hits the ground.

Here, we can observe that the carts are shifted to the right or left by one space. Consequently, the potential energy will also change in response to the motions.

To see a similar example:

The right question is:

Cherise sets identical magnetic carts on two tracks. At the end of each track is a blue magnet that cannot move. Cherise can move the carts to one space to the left or one space to the right. Which movement will result in the largest increase in potential energy?

a. Moving the cart on Track 1 one space to the right (→).

b. Moving the cart on Track 2 one space to the left (←).

c. Moving the cart on Track 2 one space to the right (→).

d. All these movements will result in the same change in potential energy because they each move a cart the same distance.

A copper ornament has a mass of 0.0693 Kg and changes from a temperature of 18 degrees celcius to 26 degrees Celsius. How much h
zhuklara [117]

Answer: 216.2 J

Explanation: The heat energy of copper is the expressed in Q=mc∆T. First make sure that the mass 0.0693 kg is converted into grams to cancel both units.

Q= 69.3 g x 390 J/g°C x 26 °C-18°C = 216.2J

If the flea jumps straight up, how high will it go? (Ignore air resistance for this problem; in reality, air resistance plays a
Savatey [412]

Answer:

The flea will reach to a height of 5.2 cm.

Explanation:

Let us assume it is given that, a flea reaches a takeoff speed of 1.0 m/s over a distance of 0.50 mm.

Initial speed, u = 1 m/s

Initial distance, x = 0.5 mm

We need to find the height reached by the flea. Using third equation of motion to find it.

At maximum height, its final speed, v = 0

v^2-u^2=2ah

Here, a = -g

-u^2=-2g(h-x)\\\\1^2=2\times 9.8\times (h-0.5\times 10^{-3})\\\\h=0.052\ m

or

h = 5.2 cm

So, the flea will reach to a height of 5.2 cm.

HELP ASAP!! WILL TRY TO GIVE BRAINLIESTT!!
vfiekz [6]

If a cell is placed in a hypertonic solution, water will leave the cell, and the cell will shrink. In an isotonic environment, there is no net water movement, so there is no change in the size of the cell. When a cell is placed in a hypotonic environment, water will enter the cell, and the cell will swell.
