Juan rides his horse with a constant
speed of 18 km/h. How far can he travel
in 1/2 hour?

Answers

Answer 1

Answer:

He traveled 9km

Explanation:

To do this problem you need to use the equation which is Speed= distance/time and this problem gives you the speed which is 18 km/h and it gives you the time 1/2 hour so you write the equation 18= d/ 1/2 which his distance is 9km

which statements describe kinetic and potential energy? check all that apply.

Answers

Answer:

ACDE

Explanation:

Energy is generally described as the ability to do work by a body. There are two main forms of energy which are the kinetic energy and the potential energy.

Other energy forms stems from these two energy types.

Potential energy expressly deals with the position of a body. It is mathematically given as:

             Potential energy  = mass x acceleration due to gravity x height

It is the energy stored based on the position of particles within a medium

These description satisfies options A, C

Kinetic energy is the energy due to the motion of body. It is mathematically given as:

             Kinetic energy  = [tex]\frac{1}{2}[/tex] x mass x velocity²

Also, kinetic energy is directly proportional to the velocity of a body.

The time for a sound wave to travel between two people is 0.80 s,
The people are 256 m apart
Calculate the speed of sound in air.

Answers

Answer:

Explanation:

Using the below formula

Speed of sound = ( distance between observers) *2/(total time taken)

Now putt the given values ,

time taken = 0.80 sec

distance = 256 m

hence

V of sound= 256*2/0.80

V of sound = 640 m/sec

Which equation should be used to calculate the speed of a wave?

speed = frequency x wavelength
speed = frequency x hertz
speed = period x wavelength
speed = period x hertz

Answers

The equation should be used to calculate the speed of a wave is speed = frequency x wavelength.

What is the formula for wave speed?

The speed of a wave is calculated by the equations: V = λ . f or V = λ/T, and the unit of measurement is m/s. This speed depends on the medium: in gaseous media, the speed is lower than in solid media.

See more about wave speed at brainly.com/question/10715783

The equation should be used to calculate the speed of a wave is speed = frequency x wavelength.

What is Speed of wave?

Wave speed is the movement of a progressive wave, which is an energy-moving disturbance that takes the shape of an oscillation and moves from one place to another.

The wavelength and frequency of a wave both affect its speed. A wave's speed is a crucial factor because it enables us to estimate how quickly the wave will disperse in the medium, which is the substance or material that will carry it.

This is the water in the case of ocean waves and the air in the case of sound waves. The kind of wave and the physical properties of the medium in which it is flowing also affect a wave's velocity.

Therefore, The equation should be used to calculate the speed of a wave is speed = frequency x wavelength.

Infrared light is typically used to make images based on the temperatures of objects.

What is meant by electromagnetic spectrum?

The range of all EM radiation arranged from high to low frequency (short to long wavelength) according to their frequency or wavelength. is known as the electromagnetic spectrum (EM).

Here,

Similar to visible light, X-rays are a type of electromagnetic radiation. X-rays have a higher energy than light, on the other hand, and can penetrate most materials, including the human body.

Images of inside body tissues and structures are produced using medical x-rays.

Electromagnetic energy in the infrared region of the spectrum can be seen by them. There is a relationship between an object's temperature and the electromagnetic radiation it releases since infrared radiation is strongly related to object temperature.

Hence,

Infrared light is typically used to make images based on the temperatures of objects.

how much energy must be absorbed by water with a mass of 0.5kg in order to raise the tempature from 30c to 65c

Answers

Answer:

62760J

Explanation:

Given parameters:

Mass  = 0.5kg  = 500g

Initial temperature  = 30°C

Final temperature  = 65°C

Unknown:

How much energy is absorbed by the water  = ?

Solution:

To solve this problem, we use the expression below:

  H  = m C Δt

  H =  m  x C x (t₂ - t₁ )

m is the mass

C is the specific heat  = 4.184J/g°C

t₂ is the final temperature

t₁ is the initial temperature

So;

              H  = 500 x 4.184 x (65  - 30) = 62760J

Explanation:

A spring has a constant of 875 N/m. and the mass which will cause this spring to stretch 4.5 meters is 401.78 kg.

What is Spring constant?

The spring constant is a characteristic of a spring which is defined as the ratio of the force affecting the spring to the displacement which is caused by that force. The SI unit of spring constant is N.m⁻¹ (Newton per meter).

The spring constant is:

F = -k/ x

where, k is the spring constant

F denotes the force,

and x denotes the change in the length of the spring.

k = 875N/m

x = 4.5m

We know that

Kx = mg

m= kx/ g

m = 875 × 4.5/ 9.8

m = 401.78kg

Therefore, the mass which will cause this spring to stretch 4.5 meters is 401.78 kg.

Answers

Solution :

Using the Gauss law, the electric field intensity of a sphere is given by :

[tex]$E. 4 \pi r^2 = \frac{Q_{enc}}{\epsilon_0}$[/tex]

[tex]$E = \frac{Q_{enc}}{4 \pi r^2 \epsilon_0}$[/tex]

Now the enclosed charge inside the sphere (r<a) is

[tex]$Q_{enc}= \rho V$[/tex]

[tex]$Q_{enc}= \rho \left( \frac{4}{3} \pi r^3 \right)$[/tex]

Hence, the electric field intensity becomes as follows :

[tex]$E= \frac{\rho \left(\frac{4}{3} \pi r^3\right)}{4 \pi \epsilon_0 r^2}$[/tex]

[tex]$E =\frac{\rho r}{3 \epsilon_0}$[/tex]

Thus, the electric field inside the sphere is given by :

[tex]$\vec {E} = \frac{\rho \vec{r}}{3 \epsilon_0}$[/tex]
