Explanation:
It is given that,
Velocity of the electron,
Magnetic field,
Charge of electron,
(a) Let is the force on the electron due to the magnetic field. The magnetic force acting on it is given by :
(b) The charge of electron,
The force acting on the proton is same as force on electron but in opposite direction i.e (-k). Hence, this is the required solution.
b. heat
c. thermal energy
d. temperature
Answer:
d. temperature
Explanation:
Total internal energy of system of ideal gas is given as
here we know that
f = degrees of freedom of gas
T = absolute temperature of the gas
no here if type of gas is same then we can say that internal energy of the gas is directly dependent on the temperature of the gas
so here correct answer will be
d. temperature
The portion of internal energy directly proportional to a system's absolute temperature is referred to as thermal energy. It is the energy due to the random motions of atoms or molecules.
The portion of the total internal energy of a system that is proportional to its absolute temperature is known as thermal energy. The internal energy of a system encompasses both kinetic and potential energy of particles within a system.
Thermal energy, on the other hand, specifically refers to the portion of this energy associated with the random movement of atoms or molecules and is directly proportional to the absolute temperature. For example, when you heat a pot of water, the thermal energy of the system (the water) increases in proportion to the rising temperature.

The kinetic energy of a 1.0 kg ball thrown with an initial velocity of 30 m/s is calculated using the formula KE = 1/2 mv^2, resulting in an energy of 450 Joules.
The question you've asked pertains to calculating the kinetic energy of a ball thrown into the air. To find the kinetic energy (KE) of a 1.0 kg ball thrown with an initial velocity of 30 m/s, you can use the formula KE = ½ mv², where m is the mass of the ball and v is the velocity. Plugging in the values, you get KE = ½ × 1.0 kg × (30 m/s)² = 0.5 × 1.0 × 900 = 450 J. Therefore, the kinetic energy of the ball is 450 Joules.

Answer:
Explanation:
It is known that the oscillation period of a pendulum can be described as
,
where T is the oscillation period, L is the length of the pendulum and, g is the gravity.
Solving For the length we get:
.
We know that g equals 5 times earth's gravity,
,
and from the angular displacement graphics, it can be seen that the period is
.
Now, we can easily compute the length of the pendulum:
Explanation:
The period (time per cycle) is 1.0 s. The gravity is 5g or 49 m/s². Therefore:
T = 2π √(L / g)
1.0 s = 2π √(L / 49 m/s²)
L = 1.2 m
