C. longest wavelength

Explanation:

Photons with the lowest energy have the longest wavelength and the shortest frequency.

The energy of photons is given as:

E = hf = $\frac{h c }{∧}$

where f is the frequency of photon

h is the planck's constant

∧ is wavelength

c is the speed of light

The more the frequency, the higher the energy of the photon.

Photons with low energy have long wavelength.

An electron with a charge e and mass m is accelerated from rest for a time T by a uniform electric field that exerts a force F o

Basile [38]

Answer:

$E =\frac{F}{e}$

Explanation:

charge of the electron = e

mass of the electron = m

Force due to electric field = F

initial velocity = 0

time taken = T

Electric field is the region around a particle which is charge where in a force is exerted on another particle which is charged.

Force on electron due to presence of uniform electric field (E):

F = e E

⇒ $E =\frac{F}{e}$

Why would it be desirable to use an energy resource that does not produce greenhouse gases?

Art [367]

C. Greenhouse gases contribute to climate change

Explanation:

It is desirable to use an energy source that does not produce greenhouse gases because these gases contributes a whole lot to climate change.

Over the years, studies have shown that the primary use of fossil fuels have significant lead to changes in the climate.

Greenhouse gases are produced during the combustion of fossil fuels.
The most important gas produced in this process is the carbon dioxide.
The greenhouse gases prevents long range radiation from leaving the earth.
They waves interacts with the gases and warms the earth surface.
Anomalous concentration of the gases causes more warming of the earth surface.
This leads to a change in climate.

Where does the food you eat end up in your body?

ICE Princess25 [194]

Explanation:

the small intestine absorbs most of the nutrients in your food, and your circulatory system passes them on to other parts of your body to store or use. Special cells help absorbed nutrients cross the intestinal lining into your bloodstream.

A roller coaster is moving at 25m/s at the bottom of a hill. Three seconds later it reaches the top of the hill moving at 10m/s.

marishachu [46]

Answer:

$5 m/s^{2}$

Explanation:

acceleration is defined as the rate of change of velocity per unit time. Therefore, acceleration, $a=\frac {\triangle v}{\triangle t}$

where $\triangle v$ is change in velocity and t is time

Substituting initial and final velocities with 25 m/s and 10 m/s then using time as given in the question of 3 s then

$a=\frac {25-10}{3}=\frac {15}{3}=5 m/s^{2}$

Therefore, the acceleration is $5 m/s^{2}$

Whats the standard unit for measuring mass

stich3 [128]

Kilograms

The kilogram is the SI base unit of mass and is equal to the mass of the international prototype of the kilogram, a platinum-iridium standard that is kept at the International Bureau of Weights and Measures (BIPM)

Hope this helps!
