Which one is the dependent variable in distance, force, or work

Physics
1 answer:
Elina [12.6K]3 years ago
3 0

Answer:

Distance

Explanation:

Work can be defined as the energy transferred to a physical object by exertion of a force on the object to cause a displacement of the object. Thus, work is typically done when a person or simple machine move an object over a distance through the application of a force.

Mathematically, work done is given by the formula;

W = F * d

Where,

W is the work done

F represents the force acting on a body.

d represents the distance covered by the body.

A dependent variable is the event expected to change when an independent variable is manipulated.

Hence, distance is the dependent variable because its value changes with respect to the amount of force exerted on an object.

What is the mirror formula for curved mirrors
Reika [66]
The mirror formula for curved mirrors is:
\frac{1}{f}= \frac{1}{d_o}+ \frac{1}{d_i}
where
f is the focal length of the mirror
d_o is the distance of the object from the mirror
d_i is the distance of the image from the mirror

The sign convention that should be used in order to find the correct values is the following:
- f: positive if the mirror is concave, negative if the mirror is convex
- d_i: positive if the image is real (located on the same side of the object), negative if it is virtual (located on the opposite side of the mirror)

Briefly explain how a resonance tube works​
Lera25 [3.4K]

Answer:

As the tines of the tuning fork vibrate at their own natural frequency, they created sound waves that impinge upon the opening of the resonance tube. These impinging sound waves produced by the tuning fork force air inside of the resonance tube to vibrate at the same frequency.

Suppose a skydiver (mass=75kg) is falling toward the earth when the skydiver is 100m above the earth he is moving at 60m/s at th
IRISSAK [1]

Given:

Mass(m)=75kg

Height (h) =100m

v(velocity)=60m/s

a(g)=9.8m/s^2(since it is a free falling object)

Now we know that

v=u+at

We know that

Potential energy=mgh

Where m is the mass

g is the acceleration due to gravity

h is the height above the ground

Substituting the above values we get

Potential energy=75 x 9.8 x 100

=73500N

Now kinetic energy =1/2mv^2

Where m is the mass

v is the velocity

Kinetic energy= 1/2 (75x60 x 60)

Kinetic energy=135000N

Now mechanical energy=

Kinetic energy+ Potential energy

Substituting the values in the above formula we get

Mechanical energy= 73500+135000

=208500N

The gravitational force acting on various masses is measured on different planets. Measured values for the forces acting on the
tatyana61 [14]

we Know that gravitational field strength(g) at a point on a planet  is equal to  gravitational force exerted per unit mass placed at that point.

It Means,

g=F/m

Here,

g=gravitational field strength

F=Gravitational force

m=Mass

Case A

planet force =10 and mass= .5

g1=F/m

g1=10/.5

=100/5

g1=20m/s

case B

F=30 and m=2

therefore g2=30/2

g2=15m/s^2

case C

F=45 and m=3

g3=45/3

=15m/s^2

case D

g4=60/6

g4=10m/s^2

from above results it is clear that the gravitational field strength of planet D is minimum which is 10m/s^2 and gravitational field strength of planet A is maximum which is 20m/s^2
