Answer:

a) f = 1m × 2 × (5A / √2) × (5A / √2) / 0.003m = 0.00166... (66 is repeating)

b) The currents on two wires on a AC chord are always moving in opposite direction and so they are always replusing.

c) There needs to be a sheath to dampen the replusing, fluctuating force of the wires.

a) v = √( ( (-2)(-1.6 × 10^(-16))(3000V) ) / (2.84 × 10^(-20)kg) ) = 5.81227 × 10^3

b) Any ion transversing a chamber having a magnetic field will deflect.

c) The direction of the electric field is vertical because it's perpendicular to the plates. The electric field magnitude is independent from the magnitude of the magnetic field and charge. So it's not possible to find the magnitude of the electric field, without knowing the voltage on the plates, the distance between the plates, and the dielectric constant.

d) Assuming the mangetic field remained, the path of the negative ions will be deflected vertically given that the magnetic field is horizontally perpendicular to the negative charged ions movement.

Sorry it took so long :) If anything is incorrect please let me know.

The sun doesn't set during what season and at what latitude?

Dahasolnce [82]

Answer: summer and greater than 66°N

Explanation:

Summer is the most appropriate season in which the sun does not set. It is a typical situation for the Arctic Circle. It is the latitude in which the sun does not set in the day and typically during the month of July. The north of this circle is a period of sunshine which last for a period of about six months in the North Pole. Summer never rises in the winter solstice (December).

A cannonball is tired with an initial speed of 40m/s and a launch angle of 30degrees from a cliff that is 25m tall. a. What is t

ella [17]

Answer:

Part a)

$t = 5.1 s$

Part b)

$x = 176.7 m$

Explanation:

Initial speed of the launch is given as

$v_i = 40 m/s$

angle = 30 degree

Now the two components of the velocity

$v_x = v_i cos30$

$v_x = 34.6 m/s$

similarly we have

$v_y = v_i sin30$

$v_y = 20 m/s$

Part a)

Now to find the time of flight we will have

$\Delta y = v_y t + \frac{1}{2}at^2$

$-25 = 20 t -\frac{1}{2}(9.81)t^2$

$t = 5.1 s$

Part b)

Distance at which the ball will land is given as

$x = v_x t$

$x = 34.6 (5.1)$

$x = 176.7 m$

Part c)

Since x direction there is no acceleration so it will move with uniform speed while in y direction it will accelerate due to gravity

A basketball has a coefficient of restitution of 0.821 in collisions with the wood floor of a basketball court. The ball is drop

Tanya [424]

Answer: The height of its fourth bounce = 0.43m

Explanation:

The coefficient of restitution denoted by (e), is the ratio that shows the final velocity to initial relative velocity between two objects after collision

IT is given by the formula in terms of height as

Coefficient of Restitution, e = √(2gh))/√(2gH) = √(h/H)

Where

Coefficient of Restitution, e= 0.821

H = 2.07 m

At fourth bounce , we have that

Coefficient of Restitution, e⁴ =√(h₄/H)

Putting the given values and solving , we have,

e⁴ =√(h₄/H)

= 0.821⁴ = √(h₄/2.07)

(0.821⁴ )² =h₄/2.07

0.2064 x 2.07 = 0.427 = 0.43

At fourth bounce, h₄ height = 0.43m

2 cannons fire projectiles upwards with the same velocity. The

dybincka [34]

Answer:

Explanation:

Given

Two projectile is fired vertically upward

One has 4 times the mass of other

When Projectile is fired their trajectory is independent of mass of object. Also if they launched with same speed then both achieved same maximum height in same time and will hit the ground at the same moment.
