Answer:
The z-component of the force is 
Explanation:
From the question we are told that
The charge on the particle is 
The magnitude of the magnetic field is 
The velocity of the particle toward the x-direction is 
The velocity of the particle toward the y-direction is
The velocity of the particle toward the z-direction is
Generally the force on this particle is mathematically represented as
So we have
substituting values
 + [(5.58*10^{4}) (0.700)]\r y)](https://tex.z-dn.net/?f=%5C%3D%20F%20%20%3D%20%287.7%20%2A10%5E%7B-8%7D%29%28%5B%20%28-2.61%2A10%5E%7B4%7D%29%20%280.700%29%5D%28-%5Cr%20%20z%29%20%2B%20%5B%285.58%2A10%5E%7B4%7D%29%20%280.700%29%5D%5Cr%20y%29)
So the z-component of the force is

Given:
The mass of the copper cylinder is: m = 76.8 g = 0.0768 kg
The change in the temperature is: T = 86.5 deg C - 19.5 deg C = 67 deg C
The specific heat is: c = 0.092 cal/g.C
To find:
Heat energy needed to heat the copper cylinder.
Explanation:
The specific heat is defined as the amount of heat energy needed to raise the temperature of a substance by one degree celcius.
The expression relating heat Q, mass m, specific heat c and temperature difference T is:
Substitute the values in the above equation, we get:
Final answer:
473.40 calories of heat is required to heat the copper cylinder.
The process of making a heavy (single (a part of an atom) from two lighter than the original nuclei n<span>uclear is commonly known as the Nuclear Fission. It is called a nuclear reaction, due to it realizes a huge about of energy.</span>
Answer: Option (c) is the correct answer.
Explanation:
Thermal energy is defined as the kinetic energy present within the molecules of a substance due to their movement.
Thermal energy can be transferred from one object to another.
On the other hand, thermal energy is the sum of both potential and kinetic energies present in a substance.
Basically, thermal energy is a part of internal energy.
Hence, we can conclude that the statement, internal energy is the total potential and kinetic energies in a substance, and thermal energy is the part of internal energy that can be transferred to another substance, best describes the difference between internal and thermal energy.
Answer:
The direction should be in the positive x direction.
Explanation:
Given that
Electric filed E= 410 V/m (In Negative y direction)
V= 9.1 x 10 ⁵ m/s
As we know that
F= E q + q.V x B
Given that protons is moving constant speed so ,F=0
F= E q +q. V x B
0= E + V x B
E = -V x B
- 410 j = - ( 9.1 x 10 ⁵ k x B i)
The direction should be in the positive x direction.
