Answer:

Both are at the side of the spectrum that has the lowest frequency

Explanation:

If electromagnetic waves are arranged in the order of the energy from highest to lowest energy range then we will have

1). Gamma rays

2) X rays

3) Ultraviolet rays

4) Visible light

5) Infrared waves

6) Microwaves

7) Radio waves

Now as per energy range we can say that both microwaves as well as radio waves must have small energy range and longer wavelength as compare to visible light.

SO correct answer is

Both are at the side of the spectrum that has the lowest frequency

The density of an object determines whether it will float or sink in another substance. An object will float if it is less dense than the liquid it is placed in. An object will sink if it is more dense than the liquid it is placed in.
So since the boat has a lower density than the water, it will float.
So the answer is choice B

What is the speed of a wave if the wavelength is 200 m and the period is 20 s?

goblinko [34]

Here is your answer

We know that

Velocity = Wavelength/Time period

Here,

Wavelength = 200m

Time period= 20 secs

So,

Velocity= 200/20 m/s

v= 10m/s

What is time taken by the stone ?

SSSSS [86.1K]

The time taken by the stone to hit the ground would be 5.12 seconds.

<h3>What are the three equations of motion?</h3>

There are three equations of motion given by Newton

The first equation is given as follows

v = u + at

the second equation is given as follows

S = ut + 1/2×a×t²

the third equation is given as follows

v² - u² = 2×a×s

Keep in mind that these calculations only apply to uniform acceleration.

As given in the problem, a stone is dropped from the helicopter which is ascending at the speed of 19.6 m/s

height(S) = 156.8 meters

initial velocity(u) = -19.6 m/s

acceleration(a) = 9.81 m/s²

By using the second equation of motion given by newton

S = ut + 1/2at²

S = 156.8m ,u= -19.6 m/s , a= 9.81 m/s² and t =? seconds

156.8= -19.6t + 9.81t²

t = 5.12 seconds

Thus, the time taken by the stone to hit the ground would be 5.12 seconds.

(1 point) Suppose a spring with spring constant 1 N/m is horizontal and has one end attached to a wall and the other end attache

fredd [130]

Answer:

Explanation:

Given that,

The spring constant

K = 1N/m

Frequency of motion

f = 14Hz

We want calculate the mass m?

The frequency of spring system is related to the mass by

From w = √k/m

Where w = 2πf

f = 1/2π √k/m

Where,

w is angular frequency in rad/s

m is mass of object attached in kg

k is the spring constant in N/m

f Is the frequency in Hz

Then, make m subject of formula

Multiply both sides by 2π

2πf = √k/m

Square both sides

4π²f² = k/m

Then, k= 4π²f² × m

m = k / 4π²f²

m = 1 / (4π² × 1.4)

m = 1 / 55.27

m = 0.0181 kg

m= 18.1 g

The mass of the object attached in 18.1 g or 0.0181 kg
