Answer:
Heat capacity, Q = 2090 Joules.
Explanation:
Given the following data;
Mass = 100 grams
Specific heat capacity = 4.18 J/g°C.
Temperature = 5°C
To find the quantity of heat required;
Heat capacity is given by the formula;
Where;
Q represents the heat capacity or quantity of heat.
m represents the mass of an object.
c represents the specific heat capacity of water.
t represents the temperature of an object.
Substituting into the formula, we have;
Heat capacity, Q = 2090 Joules.
To develop this problem, we will apply Einstein's relationship which is in charge of the work done with the kinetic energy of the body versus the total energy of the system.
The energy can be calculated as
Here,
h = Planck's Constant
f = Frequency
Our values are given as,
Therefore the Energy is
Then,
Applying the Einstein Relation we have that
Therefore the maximum kinetic energy for an electron dislodged fromthe surface by the radiation is 7.68eV
Mass is <span>is a dimensionless quantity representing the amount of matter in a particle or object. The more mass something has, the more energy is used to lift it.</span>
Answer:
Explanation:
The person on the side of the road will see the ball fall straight down, Once the person riding on the pickup truck throw the ball backward with the same speed as the truck relative to the ground,
The ball is seen moving backward by the person on the truck
Answer:
500uF
Explanation:
On the graph C (Charge/Coulomb) increases by .005 each measurement and the Voltage by 10. Capacitance= Charge/Potential difference. .005/10 =.0005 which is written as 500uF. This works since if u simply work it backwards, 1uF is 1 millionth of a Coulomb times that by 500 which gives .0005 then by 10 for Voltage and then u get the original charge.
So the answer is 500uF.
