(PLEASE HELP) : A muon (a particle with the same charge as an electron but with a mass of 1.88×10−28 kg) is traveling at 4.21×10

7 m/s at right angles to a magnetic field. The muon experiences a force of −5.00×10−12 N.
a. How strong is the magnetic field?

b. What acceleration does the muon experience?

The magnetic force is 0.74T and acceleration of the Moun is calculated as 2.66*10^16 m/s^2

Data;

  • Force (F) = -5.00*10^-12N
  • Velocity = 4.21*10^7 m/s
  • Mass(m) = 1.88 * 10 ^-28 kg

<h3>Magnetic Field Force</h3>

The formula of magnetic field force is given by

F =BqV

Let's make the magnetic field force the subject of formula

F=BqV\\B = \frac{F}{qV}\\B = \frac{5.00*10^-^1^2}{1.60*10^-^1^9 * 4.21*10^7} \\B = 0.74T

The magnetic force is 0.74T

<h3>Acceleration of the Moun</h3>

The acceleration of moun can be calculated as

F=ma\\a = F/m\\a = \frac{5.0*10^-^1^2}{1.88*10^-^2^8} \\a = 2.66*10^1^6m/s^2

The acceleration of the Moun is calculated as 2.66*10^16 m/s^2

What is the amount of thermal energy needed to make 5 kg of ice at - 10 °C to
agasfer [191]

Answer:

The amount of thermal energy needed is 15167500 joules.

Explanation:

By First Law of Thermodynamics, we see that amount of thermal energy (Q), in joules, is equal to the change in internal energy. From statement we understand that change in internal energy consisting in two latent components (U_{l,ice}, U_{l,steam}), in joules, and two sensible component (U_{s,w}), in joules, that is:

Q = U_{l,ice} + U_{s, w} + U_{s,ice} + U_{l,steam} (1)

By definitions of Sensible and Latent Heat, we expanded the formula:

Q = m\cdot (h_{f,w}+h_{v,w}+c_{ice}\cdot \Delta T_{ice}+c_{w}\cdot \Delta T_{w}) (2)

Where:

m - Mass, in kilograms.

h_{f,w} - Latent heat of fussion of water, in joules per kilogram.

h_{v,w} - Latent heat of vaporization of water, in joules per kilogram.

c_{ice} - Specific heat of ice, in joules per kilogram per degree Celsius.

c_{w} - Specific heat of water, in joules per kilogram per degree Celsius.

\Delta T_{ice} - Change in temperature of ice, measured in degrees Celsius.

\Delta T_{w} - Change in temperature of water, measured in degrees Celsius.

If we know that m = 5\,kg, h_{f,w} = 3.34\times 10^{5}\,\frac{J}{kg}, h_{v,w} = 2.26\times 10^{6}\,\frac{J}{kg}, c_{ice} = 2.090\times 10^{3}\,\frac{J}{kg\cdot ^{\circ}C}, c_{w} = 4.186\times 10^{3}\,\frac{J}{kg\cdot ^{\circ}C}, \Delta T_{ice} = 10\,^{\circ}C and \Delta T_{w} = 100\,^{\circ}C, then the amount of thermal energy is:

Q = 15167500\,J

The amount of thermal energy needed is 15167500 joules.

A 1,500 kg roller coaster is traveling at 32 m/s as it goes over a 6 meter tall hill. What is the kinetic energy of the roller c
malfutka [58]

Answer:

768000 joule

Explanation:

As we know that

K.E = 0.5 x mv2

Here m stands for mass, the measure of how much matter is in an object, and v stands for the velocity of the object, or the rate at which the object changes its position.

putting the value we get

K.E = 0.5 x (1500KG)(32 m/s)2

K.E =768000 J
