Answers

Answer:

acceleration due to gravity is always going to be 9.8m/s^2 whenever an object is freely falling.

Explanation:

You could also divide 49.1 m/s by 5s to get an acceleration of 9.8 m/s^2 as well.

What are electromagnetic waves?

Answers

Answer:

Em are waves that are created as a result of vibrations between an electric field and a magnetic field.

Explanation:

Answer:

Electromagnetic waves or EM waves are waves that are created as a result of vibrations between an electric field and a magnetic field. In other words, EM waves are composed of oscillating magnetic and electric fields.

A changing magnetic field will induce a changing electric field and vice-versa the two are linked. These changing fields form electromagnetic waves.This means that electromagnetic waves can travel not only through air and solid materials, but also through the vacuum of space.

What makes the eardrum vibrate?

Answers

Answer:

The sound waves are gathered by the outer ear and sent down the ear canal to the eardrum. The sound waves cause the eardrum to vibrate, which sets the three tiny bones in the middle ear into motion. The motion of the three bones causes the fluid in the inner ear, or cochlea, to move.

~+lil more info+~

The sound waves go through the ear canal into the middle ear, which includes the eardrum (a thin layer of tissue) and three tiny bones called ossicles. The sound causes the eardrum to vibrate. The ossicles amplify these vibrations and carry them to the inner ear.

A bicyclist with a mass of 50 kg is traveling at a rate of 30 m/s. It accelerates to a rate of 50 m/s in 5 seconds. What is the net force acting on the bicycle?

Answers

Answer:

200 N

Explanation:

There is only two needed factors in play here; the mass and acceleration

According to Newton's 2nd Law: F = m*a

Now Acceleration is Velocity over Time, so we have another factor in play: Acceleration = 50-30/5 = 20/5 = 4m/s^2

Net force = (50 kg)(4 m/s^2) = 50*4 = 200 Newtons

Answers

Answer:4

Explanation:

If the velocity of an airplane is doubled, then its kinetic energy will increase by a factor of four.

What is kinetic energy?

The ability of an object to do work by virtue of its motion.

The kinetic energy is represented mathematically as

K.E = 1/2 mv²

where v is the velocity with which the object is moving and m is its mass.

When the velocity is doubled, kinetic energy is

K.E' = 1/2 m(2v)²

K.E' =4 x ( 1/2 mv²)

Thus,  airplane's kinetic energy will increase by a factor of four.

Which element accumulates in the environment due to the use of
fertilizers?
A. oxygen
B. hydrogen
C. nitrogen
D. carbon

Answers

To Find :

Which element accumulates in the environment due to the use of  fertilizers.

Solution :

Most of the fertilizers used in daily practice are nitrogen fertilizers .

When soil became waterlogged, soil organisms take the oxygen they need from nitrates, leaving the nitrogen in a gaseous form which escapes into the air.

Also, nitrogen is very stable and did not participate in most of the reactions.

So, nitrogen is accumulates in the environment .

Therefore, option C. is correct.

A compressed spring stores 720 J of energy. A 1 kg block rests on the end of the spring. The spring is released and comes back to its uncompressed length pushing the block away. What is kinetic energy of the block as it leaves the spring? What is the speed of the block at this instant?

Answers

Answer:

the kinetic energy of block will be equal to energy stored in spring ie 720 J

the speed of block will be 37.9 m/s

Explanation:

E = m v^2 / 2

v = sqrt (2 * E / m)

v = sqrt (2 * 720 J / 1 kg) = 37.9 m/s

Janet jumps horizontally off a high diving platform with a velocity of 2.76 m/s and lands in the water 2.3 s later. How high is the platform? The acceleration of gravity is 9.8 m/s. Answer in units of m.

How far from the base of the platform does she land? Answer and units of m.​

Answers

Answer:

(a) Let the height of the platform is h meter,

=>By s = ut + 1/2gt^2

=>h = 0 + 1/2 x 9.8 x (2.3)^2

=>h = 25.92 m

(b) By R = [Ux] x t

=>R = 2.47 x 2.3

=>R = 5.68 m

Explanation:

Explanation:

From the exercise we know the initial horizontal velocity and the time that Janet takes to land in the water

a) Knowing the formula for free falling objects, we can calculate how high is the platform

At t=2.3m the position of Janet is y=0m

So, the platform is 26m tall

b) According to dynamics the displacement of an object can be analyze using the following formula:

So, Janet lands 6 m far from the base of the platform

Which best illustrates projectile motion

What is projectile motion?

Projectile motion is the motion of an artifact thrown or projected into the air that is only affected by gravity's acceleration. The object is known as a projectile, and its path is known as its trajectory.

Any object that is cast, fired, flung, heaved, hurled, pitched, tossed, or thrown is considered a projectile.

Throwing a ball straight up, kicking a ball at an angle to the horizontal, or simply dropping things and letting them fall are all examples of projectile motion.

The pictorial diagram of a person hopping sideways in five different positions best illustrates projectile motion. The starting and ending points are on the ground.

Thus, the correct option is D.
