Answer: lambda
, nu
, and 100E
Explanation:
The energy
of a photon is given by:
(1)
Where:
is the Planck constant
is the frequency
On the other hand, we have an expression that relates the frequency of the photn with its wavelength
:
(2) where
is the speed of light
Substituting (2) in (1):
(3) This is the energy for a single photon
For 100 photons, the energy is:
(3)
Where the wavelength and the frequency of the light remains constant.
Therefore, the answer is:
,
, and 100E
Total distance travelled by the car is 'd'
<span>distance trveled before the brakes were applied = v_o * t </span>
<span>distance travld with brakes = d - v_o*t </span>
<span>applying the formula: v^2 - u^2 = -2 a * s </span>
<span>=> 0 - v_o^2 = -2 * a_x * (d- v_o*t) </span>
<span>=> a_x = (v_o^2)/ ( 2 (d-v_o*t)</span>
Answer:
n. Abbr. BMR. The rate at which energy is used by an organism at complete rest, measured in humans by the heat given off per unit time, and expressed as the calories released per kilogram of body weight or per square meter of body surface per hour.
Explanation:
Metals tend to readily lose electrons and form cations. Most of them react with atmospheric oxygen to form metal oxides. However, different metals have different reactivities towards oxygen (unreactive metals such as gold and platinum do not readily form oxides when exposed to air
Answer:
It shows that the gravitational force is directly proportional to the product of masses of two bodies and inversely proportional to the square of distance between them, So, as the mass of bodies increases, the gravitational force increases and with the increase of distance between them, the gravitational force decreases.
