Calculate the potential energy stored in an object of mass 50 kg at a height of 20 m from the ground.
(g=10 m/s2)

PLEASEEE FASTTTTT PLEASEEE

Answers

Answer 1

Answer:

potential energy=mgh

=50×10×20

=10000 J

Answer 2

Answer:

[tex]\huge\boxed{\sf P.E. = 10 kJ}[/tex]

Explanation:

Given Data:

Mass = m = 50 kg

Height = h = 20 m

Acceleration due to gravity = g = 10 m/s²

Required:

Potential Energy = P.E. = ?

Formula:

P.E. = mgh

Solution:

P.E. = (50)(20)(10)

P.E. = 10,000 Joules

P.E. = 10 * 10³ Joules (10³ = Kilo)

P.E. = 10 kJ

An object of mass 100kg is moving with a velocity of 5m/s. Calculate the kinetic energy of that object

Answers

Answer:

1250 J

Explanation:

KE = 1/2(100 kg)(5 m/s)^2

KE = 1250 J

Given m=100kg
V=5m|s
Required KE=?
Solution KE=1/2mv^2
=1/2 100kg(5m/s)^2
=50kg*25(m/s)^2
=1250J

A car is moving at 80km/h accelerates to pass a truck. Five seconds later the car is moving at 100km/h. What is the Acceleration of the car? Please show the equation, Ty.

Answers

Answer/Explanation:

Acceleration is the rate of change of the velocity of an object that is moving. This value is a result of all the forces that is acting on an object which is described by Newton's second law of motion. Calculation of such is straightforward, if we are given the final velocity, the initial velocity and the total time interval. We can just use the kinematic equations. Fortunately, we are given these values. So, we calculate as follows:

acceleration = v - v0 / t

acceleration = (80 mph - 50 mph) ( 1 h / 3600) / 5 s

acceleration = 1.67 x 10^-3 m / s^2

a = V2-V1 ÷ Δt
a = 27.78 m/s - 22.2 m/s ÷ 5 seconds
a = 1.116 m/s ²

*you needed to convert the km/h to m/s for proper evaluation, which is what i did*

An astronomer writes down the following for an object in the night sky: azimuth 364˚ and altitude 93˚, what is wrong with the values?

Answers

I think 25 degrees . I am definitely going to be wrong probably though

If your azimuth is larger than 180 degrees, multiplying it by 180 degrees to find your rear azimuth will result in an azimuth that is greater than 360 degrees.

What azimuth 364˚, altitude 93˚, what is wrong with values?

A circle has 360 degrees, thus if your azimuth is higher than 180 degrees, multiplying it by 180 degrees to find your back azimuth will result in an azimuth higher than 360 degrees.

Because many ancient calendars had 360 days, it may be because the stars appeared to rotate around the north star at a rate of around 1 degree every day that azimuth is measured using a 0-360° interval. Azimuth is utilized outside of astronomy in disciplines like navigation and geology.

Therefore, Whereas an object at 90 degrees height is directly overhead, one at 0 degrees altitude is just above the horizon.

Which most likely has the greatest conductivity? a warm plastic rod a cool rubber tube a cool silver strip a warm copper wire

Answers

Answer:

Copper

Explanation:

Plastic and Rubber are both bad conductors of electricity so it cant be those

Copper is a good conducter of electricity since it warms up it allows electrons to move easily faster than silver.

A cool silver strip most likely has the greatest conductivity.

What is meant by conductivity ?

The ability of a material to transmit heat or an electric charge through it is measured by its conductivity.

Here,

A conductor is a substance that offers extremely little resistance to the transmission of thermal or electrical energy.

Metals, semiconductors, and insulators are the three main categories of materials. The least conductive materials are called insulators which include ceramic, wood, and plastic, while metals are the most conductive materials.

Of all metals, silver has the highest electrical conductivity. In actuality, silver is the benchmark metal against which all other metals are measured for conductivity.

On a scale of 0 to 100, silver scores a perfect 100, followed by copper at 97 and gold at 76.

Hence,

A cool silver strip most likely has the greatest conductivity.
