Answer: Option (c) is the correct answer.

Explanation:

When we have to convert temperature from kelvin to degree celsius then we subtract 273 from the given temperature.

Whereas if we have to convert temperature from degree celsius to kelvin then we add 273 into the given temperature.

Therefore, convert 5 degree celsius temperature into kelvin as follows.

                        (5 +  273) Kelvin

                       = 278 k

Thus, we can conclude that 278 k  temperature is equal to 5^o{C}.

Two students have fitted their scooters with the same engine. Student A and his
sammy [17]

The force exerted by student A with his scooter is 306 N and that of student B is 204 N.

<h3>Force applied by each student</h3>

The force exerted by each student is calculated from Newton's second law of motion.

F = ma

where;

  • m is mass
  • a is acceleration

F(A) = 127.5 x 2.4

F(A) = 306 N

F(B) = 120 x 1.7

F(B) = 204 N

Thus, the force exerted by student A with his scooter is 306 N and that of student B is 204 N.

A 0.45 kg soccer ball changes its velocity by 20.0 m/s due to a force applied to it in 0.10 seconds. What force was necessary fo
frutty [35]

Answer:

90 N

Explanation:

The force applied to the ball is given by:

F=\frac{\Delta p}{\Delta t}

where

\Delta p is the change in momentum of the ball

\Delta t is the time taken

The change on momentum of the ball is:

\Delta p=m\Delta v=(0.45 kg)(20 m/s)=9 kg m/s

So, the force applied is

F=\frac{9 kg m/s}{0.10 s}=90 N

A coil of wire with 50 turns lies in the plane of the page and has an initial area of 0.180 m2. The coil is now stretched to hav
butalik [34]

Answer:

Explanation:

Given that,

Number of turns of coil

N = 50 turns

Initial area of plane

A1 = 0.18 m²

The coil it stretch to a no area in time t = 0.1s

No area implies that the final area is 0, A2 = 0 m²

Constant magnetic field strength

B = 1.51 T

EMF?

EMF is given as

Using far away Lenz law

ε = —N• dΦ/dt

Where Φ = BA

Then,

ε = —N• d(BA)/dt

Since B is constant,

ε = —N•B dA/dt

ε = —N•B (∆A/∆t)

ε = —N•B(A2—A1)/(t2-t1)

ε = —50 × 1.51 (0—0.18)/(0.1—0)

ε =—75.5 × —0.18 / 0.1

ε = 135.9 V

The induced EMF is 135.9V

Fleming’s left hand rule stated that if the index finger points toward magnetic flux, the thumb towards the motion of the conductor, then the middle finger points towards the induced emf.

Since the area lines in the plane, then the induced emf will be out of the page
