54 kg person, diving into a pool
at a speed of 30 m/s?

Answers

Answer:

Explanation:

Formula

KE = 1/2 m v^3

Givens

m  = 54 kg

v = 30 m/s

Solution

KE = 1/2 54 * 30^2

KE = 1/2 54 * 900

KE = 27 * 900

KE = 24300 Joules

The work done in lifting a brick of mass 2kg through a height of 5m above the ground will be
(A)2.5J
(B)10J
(C)50J
(D)100J

Answers

Answer:

D. 100 J

Explanation:

Given

Mass (m) = 2 kg

Height (h) = 5 m

Acceleration due to gravity (g) = 10 m/s²

Now

Work done(W)

= m * g * h

= 2 * 10 * 5

= 100 Joule

Hope it will help :)❤

The work done in uplifting a brick having a mass of 2kg along with a height of 5m above ground level would be:

D). 100 J

Given that,

Mass of the brick [tex]= 2Kg[/tex]

Height of the brick [tex]= 5m[/tex]

As we know,

Work Done (W) [tex]= mgh[/tex]

where

m = Mass

g = Acceleration due to gravity

h = height

A.T.Q.

By substituting the given values, we get;

[tex]Work Done (W)[/tex] [tex]= 2[/tex] × [tex]10[/tex] × [tex]5[/tex]            (taking [tex]g = 10 m/s^2[/tex])

[tex]= 100 J[/tex]

Thus, the work done is 100 J and hence, option D is the correct answer.

if the reference point changes, the
_____ of position changes, but the actual position does not change

Answers

Answer:

description

Explanation:

Motion can be defined as a change in the location (position) of a physical object or body with respect to a reference point.

This ultimately implies that, motion would occur as a result of a change in location (position) of an object with respect to a reference point or frame of reference i.e where it was standing before the effect of an external force.

Mathematically, the motion of an object is described in terms of acceleration, time, distance, speed, velocity, displacement, position, etc.

A reference point refers to a location or physical object from which the motion (movement) of another physical object or body can be determined.

For example, a point on a map is considered to be a reference point because it represents the starting point of an object or person in motion.

If the reference point changes, the description of position changes, but the actual position does not change.

Para pagar la entrada al circo y comprar palomitas: Daniela y María van a cooperar con $65.50 cada una y Francisco y Javier con $69.50 cada uno. ¿Cuánto dinero van a reunir?

Answers

Answer:

Reunirán $270.

Explanation:

Para pagar la entrada al circo y comprar palomitas Daniela y María van a cooperar con $65.50 cada una. Entonces para calcular el dinero que van a reunir entre ambas debes sumar lo que aporta cada una:

$65.50 + $65.50= $131

Por otro lado, Francisco y Javier van a cooperar con $69.50 cada uno. De igual manera, para calcular el dinero que van a reunir entre ambos debes sumar lo que aporta cada uno:

$69.50 + $69.50= $139

Para conocer el dinero total recaudado, debes sumar lo que aportan tanto ellas como ellos. Esto es:

$131 + $139= $270

Reunirán $270.

b. What is the purpose of the normal line in the diagram?
c. State which angle does x represent.
d. What's the type and direction of the image formed by the mirror?

Answers

Answer:

a) ray horizontal and ray leaves his feet

b) The normal line respect to which the angles are measured,

c) The angle x is the reflected angle

d) virtual image,  right image

Explanation:

a) To complete the rays, you must draw a horizontal ray at the height of the man's head, this ray touches the mirror perpendicularly, therefore it bounces in the same direction.

The other ray leaves his feet and touches the mirror at one point, it is reflected with the same angle, by the law of reflection and reaches the eyes of man, the brain creates an extension of this ray and at the point of the floor creates the image point.

b) The normal line is a line perpendicular to the surface with respect to which the angles are measured,

c) The angle x is the reflected angle, which is equal to the incident angle according to the law of reflection

d) The image is formed by the prolongation of the rays of light, therefore it is a virtual image and as it has the same direction of the man it is a right image
