A solenoid used to produce magnetic fields for research purposes is 2.5 mm long, with an inner radius of 30 cmcm and 1300 turns of wire. When running, the solenoid produced a field of 1.4 TT in the center. Part A Given this, how large a current does it carry
Answer:
2.14 A
Explanation:
L = 2.5 mm, N = 1300, B = 1.4 T, find I
B = μ₀N*I/L
so I = B*L/(μ₀N) = 1.4 * 0.0025/(4π x 10⁻⁷ x 1300) = 2.14 A

3. For a constant launch speed, what angle produces the same range
as a launch angle of
a) 30°?
b) 15°?
Answer:
A) 60 degrees B) 75 degrees
Explanation:
You use complementary angles to solve this. A complementary angle is when two angles add up to 90 degrees. For A), it says that the angle is 30 degrees. So you can do 90 minus 30 and you get 60. For B), it’s says the angle is 15 degrees. So you do 90 minus 15 and you get 75 degrees.
1. An express train, traveling at 36 m/s, is accidentally sidetracked onto a local train track. The express engineer spots a local train 100 m ahead on the same track and traveling in the same direction at a constant 11 m/s. The local engineer is unaware of the situation. The express engineer jams on the brakes and slows the express at 3.0 m/s2. (a) To determine whether the trains collide, use kinematics to calculate their positions when the express train stops: i. How much time will it take the express train to stop? ii. In that time, how far will the express train have moved? iii. In that time, how far will the local train have moved? iv. Based on the results of ii. and iii., do the trains collide? Explain.
Answer:
(i) 12 seconds
(ii) 216 meters from the initial position
(iii) 132 meters from the initial position
(iv) No
Explanation:
Speed of express train =36 m/s
Speed of local train =11 m/s
The initial distance between the local train and passenger train =100 m.
Due to the application of breaks, the express train slows at the rare of [tex]3.0 m/s^2.[/tex]
So, the acceleration of the express train, [tex]a=-3 m/s^2[/tex].
(i) Let t be the time the express train takes to stop.
From the equation of motion,
v=u+at
where, v: final velocity, u: initial velocity, a: constant acceleration, t: time taken to change the speed from u to v.
In this case, v=0, u=36 m/s, [tex]a=-3 m/s^2[/tex]
So, 0=36+(-3)t
[tex]\Rightarrow t= 36/3=12[/tex] seconds.
(ii) To compute the distance traveled, s, till the express train stops, using
[tex]v^2=u^2+2as[/tex]
[tex]\Rightarrow 0^2=36^2+2(-3)s[/tex]
[tex]\Rightarrow s=\frac{36\times36}{6}[/tex]
[tex]\Rightarrow s=216[/tex] meters.
(iii) The local train is moving at a speed of 11 m/s
So, in 12 seconds, the distance, d, traveled by the local train
d= 11x12=132 meters [as distance= speed x time]
(iv) Let 0 be the reference position which is the initial position of the express train.
So, at the initial time, the position of the local train is at 100m.
After 12 seconds:
The position of the express train is at 216 m [using part (ii)]
and the position of the local train is at 100+132=232m [using part (iii)].
So, the local train is still ahead of the express train, hence the trains didn't collide.

A motorcycle accelerates at 10 m/s2 to reach a final velocity of 50 m/s from rest. How much time passed during the acceleration?
Answer:
t = 5 s
Explanation:
We'll need this equation:
Vf = Vi + at
Rearranging the equation to solve for time, we get:
t = ( Vf - Vi ) / a
Plugging in what we know, we get:
t = ( 50 m/s - 0 m/s ) / 10 m/s^2
t = 5 s

You are given the right triangle shown. Which of the following equations would be a correct way to solve for the missing information
A. I and then II or III
B. I and II only
C. II or III only
D. You must use all
Answer:
Option A. I and then II or III
Explanation:
From the question given above, the following data were obtained:
Angle = θ
Opposite = 16 m/s
Adjacent = 24 m/s
Hypothenus = v
i. The value of θ can be obtained by using Tan ratio as show below:
Tan θ = Opposite / Adjacent
Opposite = 16 m/s
Adjacent = 24 m/s
Tan θ = 16 / 24
ii. Cos θ = Adjacent /Hypothenus
Adjacent = 24 m/s
Hypothenus = v
Cos θ = 24 / v
Cross multiply
v × Cos θ = 24
Divide both side by Cos θ
v = 24 / Cos θ
iii. Sine θ = Opposite /Hypothenus
Opposite = 16 m/s
Hypothenus = v
Sine θ = 16 / v
Cross multiply
v × Sine θ = 16
Divide both side by Sine θ
v = 16 / Sine θ
From the above illustrations, we can use (i) to obtain θ then we can use (ii) or (iii) to obtain the value of v.

Define kinetic energy and write a statement about how kinetic energy is affected as velocity increases.
Answer: Kinetic energy is the energy of mass in motion. Because kinetic energy is proportional to the velocity squared, increases in velocity will have an exponentially greater effect on translational kinetic energy.
Explanation: Google
A moving object's kinetic energy is directly proportional to both its mass and the square of its velocity.
How does kinetic energy gets changed ?
An object with twice as much mass and the same speed will have twice as much kinetic energy, whereas an object with twice as much mass and the same speed will have four times as much kinetic energy.Kinetic energy is the kind of energy an object or particle has because it moves. When a net force is applied to an object, which is work that transfers energy, the object accelerates and gains kinetic energy. A moving object or particle's kinetic energy is a property that is affected by its mass as well as its motion. Translation (movement along a path from one location to another), rotation about an axis, vibration, or any combination of these motions can be the type of motion.In the meter-kilogram-second system, the joule is the energy unit. The kinetic energy of a two-kilogram mass traveling at a speed of one meter per second, which is slightly more than two miles per hour, is one joule, or something like 4.4 pounds on Earth. The unit of energy in the centimeter-gram-second system is the erg, or 10^7 joules, which is the same as the kinetic energy of a mosquito in flight. On the atomic and subatomic scale, smaller units of energy, such as the electron volt, are also utilized in specific contexts.To know more about kinetic energy check this:

Explanation:
potential energy (PE) is equal to the mass of the object multiplied by the acceleration due to gravity multiplied by the height of the object.
PE=mgh (g=9.8 m/s/s)
PE= (2 kg)(9.8 m/s/s)(20 m)
PE= 392 j

For a rocket traveling at 12010 m/s, by what factor does its relativistic momentum differ from its ordinary momentum
The relativistic momentum of the rocket differ from the ordinary momentum by a factor of 1.2m.
Relativistic momentum of the rocketThe relativistic momentum of the rocket is calculated as follows;
[tex]P = \frac{mv}{\sqrt{1- \frac{v^2}{c^2} } } \\\\P = \frac{m(12010)}{\sqrt{1- \frac{(12010)^2}{(3\times 10^8)^2} } } \\\\P = 12,011.2 m \ (kgm/s)[/tex]
where;
m is mass of the rocketOrdinary momentum of the rocketThe ordinary momentum of the rock is calculated from the product of mass and velocity of the rocket.
P = mv
P = 12010m (kgm/s)
Difference between the two momentumΔP = 12,011.2m - 12,010m
ΔP = 1.2m
Thus, the relativistic momentum of the rocket differ from the ordinary momentum by a factor of 1.2m.
