Answer:

Twice as much

Explanation:

Changing magnetic flux through a coil produce emf in the coil.

According to Faraday's law induced voltage is given by

∈= - N *dФ \ dt -----------( 1 )

N is number of turns of coil

Ф is flux linkage

dФ/dt is rate of change of flux

From equation (1) it is clear if rate of change of flux is the same but we  doubled the number of loops (i.e N₂= 2N₁) the voltage induced will be double.

TRUE OR FALSE : Boyle’s law states that, as the pressure of a gas increases, the volume decreases.
White raven [17]

True, but only if the temperature of the gas doesn't change ...
which is pretty hard to manage when you're compressing it.

I think Boyle's law actually says something like

       (pressure) x (volume) / (temperature)  =  constant.

So you can see that if you want to say anything about two of the
quantities, you always have to stipulate that the statement is true
as long as the third one doesn't change.

PLEASE PLEASE HELP!

Well, the relationship between the net force and mass and acceleration of an object are directly related, as per the equation - Fnet = ma.

Thus the solution is A. As the net force of an object decreases, the object's acceleration also decreases, mass is kept constant.

Two blocks are on a horizontal frictionless surface. Block a is moving with an initial velocity
AfilCa [17]

The final velocity of the block A will be 2.5 m/sec. The principal of the momentum conversation is used in the given problem.

<h3>What is the law of conservation of momentum?</h3>

According to the law of conservation of momentum, the momentum of the body before the collision is always equal to the momentum of the body after the collision.

In a given concern, mass m₁ is M, mass m₂ is 3M. Initial speed for the mass m₁ and  m₂ will be u₁=5 and u₂=0 m/s respectively,

According to the law of conservation of momentum

Momentum before collision =Momentum after collision

m₁u₁+m₂u₂=(m₁+m₂)v

M×5+3M×0=[M+3M]v

The final velocity is found as;

V=51.25 m/s

The velocity of block A is found as;

\rm V_f=\frac{(m_1-m_2)u_1}{m_1+m_2} +\frac{2m_2u_2}{m_1+m_2} \\\\  V_f=\frac{(M-3M)5+2\times3M\times0}{m_1+m_2} \\\\ V_f=2.5 m/s

Hence, the final velocity of the block A will be 2.5 m/sec.

Help me with this???
Vikentia [17]

Yo sup??

Average velocity=total distance covered/total time taken

total distance covered=4 + 8=12 miles

total time taken=6 hours

Therefore

average velocity=12/6

=2 miles/hour

Hope this helps
