Archimedes' principle says that a 15 N object is buoyed up by a force that is

Answers

Answer 1
Answer:

Answer:

  • equal to the weight of the fluid that the body displaces

Explanation:

Archimides' principle states the definition of buoyant force.

These are the imporant features of the buoyant force that you need to know:

  • Except for the very special vacuum condition, every body is immersed in a fluid.

  • The body is subject, at least, to two forces, its weight and the buoyant force.

  • The weight is the result of the gravitational attraction exerted by the planet, and is equal to the mass of the object by the gravitational acceleration (approximately 9.8 m/s² on Earth). It is directed vertically downward.

  • The buoyant force is the vertical upward force that the fluid exerts on the object and is equal to the weight of the volume of fluid displaced by the object.

  • The volume of fluid that the body displaces is equal to the immersed volume of the body.

You are in a desert on a hot day and see water in the distance. It is not really there, you see it because light bends due to a difference in the temperature of air. Which behavior of light best explains this? Select one: a. reflection b. translocation c. diffraction d. refraction

Answers

Answer:

d) refraction

Explanation:

in physics, refraction is the change of direction of a wave passing from one medium to another. refraction of light is the most commonly observed phenomenon but other waves such as sound waves and water waves also experience refraction

Answer:

B. Translocation

Explanation:

It means a change in location. It often refers to genetics, when part of a chromosome is transferred to another chromosome, you want a change in location because you are so thirsty in the desert and need water

what is the restoring force of a spring with a spring constant of a 4a and a stretched displacement of 3b?

Answers

Answer:

Thus, the restoring force is - 12 a b.

Given:

Spring constant = 4 a

Stretched displacement = 3 b

To find:

Restoring force = ?

Formula used:

The restoring force is given by,

F = -k x

Where F = restoring force

spring constant = k = 4 a

stretched displacement = x = 3 b

Solution:

The restoring force is given by,

F = -k x

Where F = restoring force

spring constant = k = 4 a

stretched displacement = x = 3 b

F = - (4 a) (3 b)

F = - 12 a b

Thus, the restoring force is - 12 a b.

What is the kinetic energy of a 1 kg ball thrown into the air with an initial velocity of 30 m/s

Answers


Welll ... we can do the math and the physics and get an answer
for you, but then we'll really want to step back into the real world
and see how feasible all of this is.

      Kinetic Energy = (1/2) (mass) (speed)²

                              = (1/2)  (1 kg)  (30 m/s)²

                              = (1/2)  (1 kg)  (900 m²/s²)

                              =     450 kg-m²/s²  =  450 joules .

That's the KE of the ball at the instant it leaves your hand,
moving at 30 m/s .  Immediately after that, we don't know
what happens to it.  It may lose speed, if you tossed it upward,
or it may gain speed, if you tossed it downward or horizontally. 
As soon as its speed changes, so does its KE.

And now, a word from the real world:
' 30 m/s ' is about 67 miles per hour, and the ball weighs a little
over 2 pounds.  Do you really think you could make that toss ?
