Rohit placed a pencil perpendicular to principal axis in front of a converging
mirror of focal length 30 cm. The image formed is twice the size of the pencil.
Calculate the distance of the object from the mirror.

Answers

Answer:

45 cm ( in my opinion)‍♀️

Explanation:

( Using the mirror formula)

1/ u + 1/v = 1/f

( introducing magnification; m into the formula )

u( 1/u + 1/v ) =u×1/f

1 + u/v =u/f

( But u/v =1 ÷v/u= 1/m)

1 +1/m =u/f

(Supposing m is actually equal to 2, and f =30 cm, then;)

1 + 1/2 =u/30

2+1= u/15

3=u/15

3×15=u

45 cm=u

Ski lift carry people along 150 m cable up the side of a mountain. Riders are lifted a total of 75 m in elevation. What is the ideal mechanical advantage of the ski lift?

Answers

Ideal Mechanical Advantage (IMA) can be found by using the formula:

IMA = ID/OD

ID = Input Distance

OD = Output Distance

In the question, we are given:

ID = 150

OD = 75

Now, solve the expression with what we have.

IMA = 150/75

IMA = 2

Therefore, the IMA is 2.

You have a large flashlight that takes 4 D-cell batteries, each with a voltage of 1.5 volts. If the current in the flashlight is 2.0 amps, what is the
resistance?
A 12 ohms
B 0.75 ohms
C 3.0 ohms
D.0.5 ohms
E. 6.0 ohms

Answers

Answer:

The answer is "C. 3.0 ohms".

Explanation:

Ohm's law states the following:,

V = IR

where:

Voltage (V) = 1.5 volts × 4 batteries = 6.0 volts

Current (I) = 2.0 amps

Resistance (R) = ? ohms

To solve for Resistance (R) the equation must be rearranged this way:

R = V / I

Then, the variables must be replaced with the known values:

R = 6.0 volts / 2.0 amp

R = 3.0 ohms

The answer is C. 3.0 ohms.

Object A has a mass of 10 kg and is moving at a velocity of 2.0
m/s. So Object A's momentum is - kg. m/s.

Answers

Answer:20kgm/s

Explanation:

Mass=10kg

Velocity=2m/s

Momentum=mass x velocity

Momentum=10 x 2

Momentum=20

Momentum=20kgm/s

The object with mass m when moving with the velocity, its momentum can be calculated. The momentum of the object A is 20 kg.m/s.

What is momentum?

Momentum is the product of mass and velocity of a moving object.

If the momentum is p, the mass of the object is 10 kg and the velocity is 2.0 m/s, then the momentum will be

p = 10 × 2.0

p = 20 kg.m/s

Thus, the momentum of the object A is 20 kg.m/s
