Answer:

The distance of the object from the concave mirror determines if it is a virtual or real image

Explanation:

Concave mirrors form both real and virtual images. When the concave mirror is placed very close to the object, a virtual and magnified image is obtained and if we increase the distance between the object and the mirror, the size of the image reduces and real images are formed.

If a 60 kg student is standing on the edge of a cliff. Find the students gravitational potential of the cliff is 30 m high

kipiarov [429]

Answer:

17640J

Explanation:

Give mass m= 60kg

Height h =30m

Since the student is standing on the edge of a cliff , acceleration due to gravity g is 9.8m/s^2

The student’s gravitational potential energy can be found by the formula

mgh

That’s 60 x 9.8 x 30

= 17640J

The kinetic energy of a ball with the mass of 0.5 kg and a velocity of 10 m/s is what

slamgirl [31]

Answer:

25J

Explanation:

Kinetic energy = 1/2 mv²

Mass = m= 0.5kg

Velocity = v = 10m/s

K. E = 1/2 x 0.5 x 10 x 10

K. E = 0.5 x 5 x 10

K. E = 2.5 x 10

K. E = 25 J

The S. I unit of energy is joules with symbol J

Define distance and displacement with illustration

Deffense [45]

Answer:

<h2>Distance</h2>

The length of the actual path travelled by a body is called distance travelled by a body.It is a scalar Quantity.It is measured in meter(m) in SI system.

<h2>Displacement</h2>

The shortest distance from initial position to the final position of a body is called displacement of the body.It is a vector Quantity.It is measured in meter(m) in SI system..

Please see the attached picture...

It is the example of distance and displacement....

Hope this helps...

Good luck on your assignment...
