Answer

3.9*10^{5}N/C

Explanation:

from the expression for determing the magnetic field strength

E=\frac{q}{4\pi e_{0}d^2 }\\

since the charge is given as

q=1.56*10^{-5}c\\

and the distance is

d=60cm=0.6m

We can calculate the constant k

K=\frac{1}{4\pi e_{0}}\\ K=\frac{1}{4\pi *8.8542*10^{-12}}\\k=8.98*10^{9}\\

if we substitute values, we arrive at

E=\frac{8.98*10^9 *1.56*10^{-5}}{0.6^2} \\E=389133.33\\E=3.9*10^{5}N/C

marishachu [46]
<h2>Average speed of transit train is 60 mph</h2>

Explanation:

Average speed of passenger train = 45 mph

Time taken from station A to station B for passenger train  = 10:00 - 6:00 = 4 hours

Distance between station A to station B = 45 x 4 = 180 miles.

Time taken from station A to station B for transit train  =  4 - 1 = 3 hours

Distance between station A to station B = Average speed of transit train x Time taken from station A to station B for transit train

180 = Average speed of transit train x 3

Average speed of transit train = 60 mph

Average speed of transit train is 60 mph

In the great shopping cart race, two students push on shopping carts. A having twice the mass of B, with the same force applied
fiasKO [112]

B. cart B

Explanation:

The acceleration of each cart is given by Newton's second law:

F=ma

a=\frac{F}{m}

where F is the force applied, a is the acceleration and m is the cart's mass.

The force F applied is the same for the two carts, however the mass of cart A (mA) is twice than the mass of cart B (mB), so we can rewrite the two accelerations:

a_A = \frac{F}{m_A}=\frac{F}{2 m_B}

a_B = \frac{F}{m_B}

we see that the acceleration of cart B is twice the acceleration of cart A, therefore cart B will move faster and will win the race.

A 1.5kg cannon is loaded with a 0.52 kg ball . The cannon is ignited and launches the ball forward with speed of 75m/s. Determin
Mila [183]

Answer:

-26 m/s (backward)

Explanation:

We can solve this problem by using the law of conservation of momentum.

In fact, the total momentum momentum of the cannon + ball system must be conserved before and after the explosion.

Before the explosion, they are both at rest, so the total momentum is zero:

p = 0

After the explosion, the total momentum is:

p=MV+mv

where

M = 1.5 kg is the mass of the cannon

m = 0.52 kg is the mass of the ball

v = +75 m/s is the velocity of the ball

V is the velocity of the cannon

Since the momentum is conserved, we can equate the two expressions:

0=MV+mv

And solving, we find V:

V=-\frac{mv}{M}=-\frac{(0.52)(+75)}{1.5}=-26 m/s

where the negative sign means the direction is opposite to that of the ball.

An object moves in simple harmonic motion with amplitude 11m and period 4 minutes. At time t = 0 minutes, its displacement d fro
Sergio039 [100]

Answer:

Explanation:

Angular velocity ω = 2π / T = 2 x 3 . 14 / (4 x 60 ) = .026 rad / s.

d = D Sin ( ωt + θ )  where  D = amplitude = 11 m θ = initial phase.

-11 = 11 sin ( 0 + θ ) = sin θ = -1 , θ = - π /2

So, d = D Sin ( ωt - θ )

         d = 11  Sin ( .026 t -  π /2  ) is the required equation.
