Which magnets need electric current for magnetism?

Answers

Answer:An electromagnet is a magnet that works with electricity. It can be switched on and off. The coils are nearly always made of copper wire because copper is such an excellent electrical conductor. Electromagnets have many uses.Permanent magnets are mainly used in small generators, and they have the advantage that they don't need a power supply. Electric magnets are iron or steel wound with wire. When electricity passes through the wire, the metal becomes magnetic and creates a magnetic field.

What does it mean with the car accelerates but in the opposite direction of the car?​

Answers

Answer:

When an object slows down, its acceleration is opposite to the direction of its motion. This is known as deceleration.

Explanation:

How long will it take for a basketball spinning on someone’s finger to stop if it undergoes and angular acceleration of -0.15 rad/s and is traveling at 27 rad/s initially? How many revolutions will it make?

Answers

The basketball's angular velocity ω at time t is

ω = 27 rad/s + (-0.15 rad/s²) t

It comes to a stop when ω = 0, which happens for

0 = 27 rad/s - (0.15 rad/s²) t

t = (27 rad/s) / (0.15 rad/s²)

t = 180 s

In this time, the ball would undergoes an angular displacement θ of

θ = (27 rad/s) t + 1/2 (-0.15 rad/s²) t ²

Plug in t = 180 s and solve for θ :

θ = (27 rad/s) (180 s) - 1/2 (0.15 rad/s²) (180 s)² = 2430 rad

One complete revolution corresponds to a turn of 2π rad, so the ball makes

(2430 rad) / (2π rad/rev) ≈ 386.747 rev

or about 387 revolutions as it slows down.

A weightlifter lifts a set of weights a vertical distance of 2.0 m. If a constant net force of 350 N is exerted on the weights, what is the net work done on the weights?

Answers

Answer:

700 Joules

Explanation:

The work done equals force times distance. Just multiply your two values there.

Side note: It would be more impressive if he'd done it in 1 second rather than 5. You know why? Because POWER=WORK/TIME. The less time it takes him to lift the weight with the same force and distance, the more powerful he is!

An archer uses 2000J of energy to pull a bow string 0.15m. What is the force constant (k) of the bow string?

Answers

The answer has to be 50 J

The spring constant of the given bow spring is equal to  1.77 × 10⁵ N/m.

What is Hooke's law?

Hooke's law can be described as a law that states that the force (F) required to extend or compress a spring by displacement linearly with respect to that displacement along a straight line.

The spring force can be represented in the form of an equation:

F = -kx

where k is a spring constant of the spring and x is the deformation of the spring. The negative sign shows that force is restoring force.

The energy that can be stored in the spring when it is stretched is given by:

E = (1/2)kx²

Given, the energy stored in the spring when it is stretched, E = 1000J

The distance by which the bow spring is stretched, x = 0.15 m

2000 =  (1/2) × k (0.15)²

k = 1.77 × 10⁵ N/m

A 3.00 kg cart on a track is pulled by a string so that it accelerates at 2.00 m/s/s. The force of tension in the string is 10.0 N. What is the force of friction on the cart?

Answers

Answer:

If the track is horizontal and the string is pulled horizontally, the friction on the cart would be [tex]4.0\; \rm N[/tex].

Explanation:

Let [tex]m[/tex] denote the mass of this cart, and let [tex]a[/tex] denote the acceleration of this cart.

[tex]m = 3.00\; \rm kg[/tex].

[tex]a = 2.00\; \rm m \cdot s^{-2}[/tex].

Apply Newton's Second Law to find the net force on this cart.

[tex]\begin{aligned}\text{Net Force} &= m \cdot a\\ &= 3.00\; \rm kg \times 2.00\; \rm m\cdot s^{-2}\\ &= 6.00\; \rm N\end{aligned}[/tex].

The following forces act upon this cart:

(downward) gravitational attraction from the earth,(upward) normal force from the track,(forward) tension from the string, and(backward) friction from the track.

Assume that the track is horizontal, and that the string was pulled horizontally. The normal force from the track would exactly balance the downward gravitational attraction from the earth. Hence, the [tex]6.00\; \rm N[/tex] net force on this cart would be equal (in size) to the size of the tension from the string ([tex]10.0\; \rm N[/tex]) minus the size of the friction from the track.

In other words:

[tex]\begin{aligned}&\text{Size of Net Force}\\ &= \text{Size of Tension} - \text{size of friction}\end{aligned}[/tex].

[tex]\begin{aligned}& 6.00\;\rm N = 10.0\; \rm N - (\text{size of friction})\end{aligned}[/tex].

[tex]\text{size of friction} = 10.0\; \rm N - 6.00\; \rm N = 4.0\; \rm N[/tex].

A wave frequency of 440 Hz travels through a medium at 343 m/s. Calculate the wavelength
for this wave.
150,920 m
1.28 m
97 m
0.078 m

Answers

Answer:

0.78 m

Explanation:

us the formula

speed = frequency x wavelength

343 = 440 x wavelength

343 / 440 = wavelength

wavelength = 0.78 m

I think the last option, you wrote wrongly, it is supposed to be 0.78 not 0.078 .

if you think I am wrong please do tell me, I will redo this.

A force of 900 N pushes a wedge 0.10 m into a log. If the work done on the log is 50 J, what is the efficiency of the wedge?
HELPPPP

Answers

Answer:

55.56%

Explanation:

We'll begin by calculating the work done in pushing the wedge. This can be obtained as follow:

Force (F) = 900 N

Distance (s) = 0.1 m

Workdone (Wd) =..?

Wd = F × s

Wd = 900 × 0.1

Wd = 90 J

Finally, we shall determine the efficiency. This can be obtained as follow:

Work output = 50 J

Work input = 90 J

Efficiency =?

Efficiency = work output / work input

Efficiency = 50 / 90 × 100

Efficiency = 55.56%

Thus, the efficiency is 55.56%
