A Canyon ball is fired from the ground level in angle of 35 from the ground at a speed of 150 m/s ignore air resistance calculat

Virty [35]

The velocity, 50 m/s, has two components - vertical and horizontal velocities.

The vertical component = 50 sin 30 = 25 m/s

The horizontal component = 50 cos 30 = 43.3 m/s

(a) Let t be the time taken for the vertical component to reach its peak from initial velocity = 25 m/s to its final velocity = 0.

Using the linear motion equation v = u - gt

0 = 25 - 10t

t = 2.5 s

Time taken to go up and down = 5 s

Time to hit the ground = 5 s

(b) Horizontal distance dealt x = 43.3 * 5 = 216.5 m

This is not the correct answer, but explains the problem thoroughly.

kap26 [50]

Answer:

emf = 15 * Area and if A is given in square meters, the units of the emf will be Volts

Explanation:

Assuming that the area of the loop of current (A) is known, the magnitude of the induced emf can be calculated using Faraday-Lenz's Law:

$emf=|-\frac{\Delta\,\Phi}{\Delta \,t} |=|\frac{A\,B}{\Delta \,t}|=|\frac{A\,(3)}{0.2}|=15\,A$

and if the area (A) is given in square meters, the emf will directly come in units of Volts.

he magnetic flux through a loop of wire decreases from 1.7 Wb to 0.3 Wb in a time of 0.4 s. What was the average value of the in

Pani-rosa [81]

Answer:

Induced emf through a loop of wire is 3.5 V.

Explanation:

It is given that,

Initial magnetic flux, $\phi_i=1.7\ Wb$

Final magnetic flux, $\phi_f=0.3\ Wb$

The magnetic flux through a loop of wire decreases in a time of 0.4 s, t = 0.4 s

We need to find the average value of the induced emf. It is equivalent to the rate of change of magnetic flux i.e.

$\epsilon=-\dfrac{\phi_f-\phi_i}{t}$

$\epsilon=-\dfrac{0.3\ Wb-1.7\ Wb}{0.4\ s}$

$\epsilon=3.5\ V$

So, the value of the induced emf through a loop of wire is 3.5 V.
