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.

Which of the following is a conversion from light energy to chemical energy?
a. turning on a stove to heat dinner
b. growing an apple tree
c. turning on a lamp
d. Turning on a blender

Answers

Answer:

A

Explanation:

turning on a stove to heat dinner because it undergoes a chemical reaction to transform into other substance

Growing up a tree is a conversion from light energy to chemical energy.

What is law of energy conservation?

Energy can neither be created nor be destroyed , it gets only transferred from one form to another.

What is photosynthesis?The process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water.In simple words by the process of photosynthesis a tree makes food for itself.

What happens when a tree grows?Tree makes food by absorbing the sunlight.The energy of the sunlight is used in making of ATPs in trees.ATP ( Adenosine triphosphate ) is used in various operations in trees.So, the sunlight is light energy which get converted into ATPs , which is chemical energy.

Thus, Growing up a tree is a conversion from light energy to chemical energy.

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

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.

Explanation:

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
