Explain why the roller coaster’s potential energy is greater at point 1 than at point 4.

lesya692 [45]

Point 1 is PROBABLY higher up than point 4.

Another possibility is that on the way from Point 1 to point 4,
a lot of people are falling out of the coaster.

We have no way to tell, because you neglected to show us
the picture that goes with this question. It's important.

Photons of infrared radiation with wavelengths longer than those of visible light will have what kind of energy compared to that

densk [106]

Answer:

Infrared photons carry lower radiation energy than the visible light.

Explanation:

Each photon carries an energy that is directly proportional to its frequency, being this proportionality constant the Planck's constant h.
So, we can write the energy of a single photon as follows:

$E = h*\nu (1)$

Since there exists an inverse relationship between wavelength and frequency, and infrared radiation has longer wavelengths, this means that its frequency is lower than the one of the visible light.
So, an infrared photon carries less energy that one of the visible light.

Determine the kinetic energy of a 1500 kg roller coaster that is moving with a

olga2289 [7]

Answer:

Explanation:

The kinetic energy of an object can be found by using the formula

$k = \frac{1}{2} m {v}^{2} \\$

m is the mass in kg

v is the velocity in m/s

From the question

m = 1500 kg

v = 35 m/s

We have

$k = \frac{1}{2} \times 1500 \times {35}^{2} \\ = 750 \times 1225 \\ = 918750$

We have the final answer as

Hope this helps you
