A current carrying wire of length 50cm is positioned perpendicular to a uniform magnetic field

1 answer:

3 0

A current-carrying wire of length 50 cm is positioned perpendicular to a uniform magnetic field. The magnetic field strength is 0.6 Tesla.

<h3>What is magnetic field?</h3>

The magnetic field is the region of space where an object experiences a magnetic force as it enters the field.

Given is the wire of length 50 cm = 0.5 m and the current is 10.0 A. There is a resultant force of 3.0 N on the wire due to the interaction of the current and field.

The relation between magnetic field strength and current is

F = ILB

Substituting 50 for L, 10 for I and 3 for F, we get the magnetic field strength B.

3 = 10 × 0.5 × B

B= 0.6 Tesla

Therefore, the magnetic field strength is 0.6 Tesla.

A 150 kg object takes 90 seconds to travel a 2500 meter straight path. It begins the trip traveling 120 meters per second and de

Nana76 [90]

The acceleration is -1.111 m/s²

Explanation:

In this case acceleration is calculated as change in velocity divided by time.

Change in velocity is 20m/s-120 m/s = -100 m/s

Time is 1.5 minutes------change it to seconds by multiplying 1.5 by 60 seconds

Acceleration will be : -100 m/s / (1.5*60) = -1.111 m/s²

A golfer strikes her tee shot with the following velocities, vx = 106 m/s & vy = 66.2 m/s. a. What is the velocity of flight

lara [203]

Answer:

a) V ≈ 125 m/s; b) Δt = 13.24 s; c) ΔS ≈ 1450 m

Explanation:

a) We have just to calculate the vector resultant.

V² = 106² + 66.2²

V² = 15618.44

V ≈ 125 m/s

b) The time of flight is equal to the time to reach the maximum height summed to the time to reach the land.

In vertical:

V = V₀ + a * t

V = 66.2 - g * t

0 = 66.2 - 9.8 * t

t ≈ 6.76 s

So: Δt = 13.24 s

c) In horizontal:

V = ΔS / Δt

106 = ΔS / 13.52 ⇒ ΔS = 106 * 13.52

ΔS = 106 * 13.52

ΔS = 1433,12

ΔS ≈ 1450 m

April and Alex are saving money to buy new phones. Each friend starts with some money and saves a specific amount each week.

qwelly [4]

First thing to note is that we are on week 0, when they start saving:

The equation for Alex is:

y=20x + 125

Know that we are on week 0, and x is our weeks, that makes our equation:

y=20(0) + 125

Which means it's really:

y=125

That means that the first one is E. 125

For the second, it shows our week 0, which is at 100.

That means that the second one is I. 100

Hope this helps!

would the phases of the moon be affected if the moon didn't make one rotation for each revolution of earth?

Aleks [24]

As long as the moon orbits the Earth in the same way, the phases will be the same.

Compare an earthquake with a Richter scale magnitude of 5.5 to one with a magnitude of 7.5.

maksim [4K]

The 7.5 is a 100 times stronger than the 5.5 . The 100 comes from the increase in scale from 5.5 to 7.5 which is an increase of two so you multiply the strength of the weaker earthquake 10^7-5=10^2=100 and that gives you the strength of the stronger earthquake!
