Explanation:
you are at the grand canyon standing at the edge of a ledge 1857 m high you have a mass of 61 kg. you decide to take a selfie to share with your science teacher when you get home which causes you to wonder how much gravitational potential energy do you have standing at the edge of this cliff
Answer:
1,110,114.6 J
Explanation:
The height is 1857m, the mass is 61 kg, and the accelaration is 9.8 m/s^2. Plug in the equation GPE=h*m*a and you get 1,110,114.6.
h= height
m= mass
a= accelaration
GPE= gravitational potential energy
If you are at the grand canyon standing at the edge of a ledge 1857 meters high you have a mass of 61 kilograms, then your gravitational potential energy at the edge of the cliff would be 1111247.37 Joules.
What is mechanical energy?Mechanical energy is the combination of all the energy in motion represented by total kinetic energy and the total potential energy stored energy in the system which is represented by total potential energy.
As total mechanical energy is the sum of all the kinetic as well as potential energy stored in the system.
ME = KE + PE
The total gravitational potential energy at the edge of the cliff would be
PE = m × g × h
PE =61 × 9.81 × 1857
PE =1111247.37 Joules
Thus, the total gravitational potential energy at the edge of the cliff would be 1111247.37 Joules.

OElectromagnetic waves only
OMechanical waves only
OElectromagnetic and mechanical waves O Longitudinal and electromagnetic waves
Answer:
A. electromagnetic waves only
Explanation:
brainliest please? :))
a) Electromagnetic waves only can travel through space
What are electromagnetic waves?Electromagnetic waves are the waves that are propagated by simultaneous period variation of electric and magnetic filed intensity .
Longitudinal wave and mechanical wave require a particular medium to travel , and in vacuum their is no medium that helps the waves to propagate because their is no particle present in vacuum . Hence , their is absence of any matter , wave cannot travel through it .
Because electromagnetic waves do not need molecule to travel and electromagnetic wave are transverse waves and they have oscillating magnetic and electric field thus do not need a medium to travel .
hence , correct option a) Electromagnetic waves only

_____ is a measure of the force of gravity pulling down on an object. it is measured in newtons (N), the common unit for measuring force
By definition, Weight is a measure of the force of gravity pulling down on an object. it is measured in newtons (N), the common unit for measuring force.
Weight is called the action exerted by the force of gravity on the body.
The mass (amount of matter that a body contains) of an object will always be the same, no matter where it is located. Instead, the weight of the object will vary according to the force of gravity acting on it.
The formula that allows you to calculate the weight of any body is:
P = m×g
where:
P = weight measured in N. m = mass measured in kg. g = acceleration of gravity measured in m/s². The acceleration of gravity g is the same for all objects that fall due to gravitational attraction, regardless of their size or composition. For example, as an approximate value on Earth, g = 9.8 m/s².
Then, the weight of an object is the force of gravity on the object, that is, the weight will vary according to the force of gravity that acts on it. So the correct answer is:
Weight is a measure of the force of gravity pulling down on an object. it is measured in newtons (N), the common unit for measuring force.

The truck takes on a load of rocks, which doubles its mass, and leaves at the same speed of 20 m/s. Quantitatively compare the kinetic energy of the truck as it left the quarry with its kinetic energy on the way to the quarry. Explain your answer.
Given that,
A truck drives to a rock quarry at a speed of 20 m/s. The truck takes on a load of rocks, which doubles its mass, and leaves at the same speed of 20 m/s.
To find,
Comparison of the kinetic energy of the truck as it left the quarry with its kinetic energy on the way to the quarry.
Solution,
Kinetic energy of an object is given by:
[tex]K=\dfrac{1}{2}mv^2[/tex]
m is the mass of the truck
[tex]K=\dfrac{1}{2}m\times (20)^2\\\\K=200m\ J[/tex]
If mass is doubled and speed is same i.e. 20 m/s, neew kinetic energy is given by :
[tex]K=\dfrac{1}{2}\times (2m)\times 20^2\\\\K=400m\ J[/tex]
It can be seen that when mass of truck is doubled, its kinetic energy gets doubled.
if you weigh 637 N on Earth's surface, how much would you weigh on the planet Mars?
Answer:
To get your answer multiply 637N by 10N/kg to get 6370kg
The mass of an object weighing 637 N on earth is 65 kg. The acceleration due to gravity on mars is 3.72 m/s². Then its weight on mars is 241.8 N.
What is gravitational force?The gravitational force is the force by which an object attracts other object into its center of mass. Earth attracts every objects into its surface and that is why we are all standing on the ground and experience a weight.
The acceleration due to gravity is the acceleration to the downward motion by gravitational force for an object. The weight of an object is the sum of its mass and acceleration due to gravity of the planet in which the object is placed.
The acceleration due to gravity of earth = 9.8 m/s²
then mass of person weighing 637 N = 637 N/9.8 m/s² = 65 Kg
acceleration due to gravity of mars = 3.72 m/s²
then weight of the mass 65 kg = 65 kg × 3.72 m/s² = 241.8 N.
Therefore, the person will weight 241.8 N at mars.

The light rays in the illustration below do not properly focus at the focal point. This problem occurs with
A. all-spherical mirrors
B. all parabolic mirrors
C. only defective spherical mirrors
D. only defective parabolic mirrors
This problem occurs with C. only defective spherical mirrors.
Spherical mirrors can be either concave or convex, depending on their shape. A perfect spherical mirror is one that has a consistent curvature across its surface, which allows all the light rays that strike it to properly converge or diverge and focus at the focal point.
However, a defective spherical mirror is one that does not have a perfect curvature across its surface. This can happen due to manufacturing errors or damage to the mirror. When a spherical mirror is defective, the light rays do not properly focus at the focal point, leading to distorted or blurred images.
On the other hand, parabolic mirrors have a unique shape that allows them to reflect incoming light rays to a single focal point, providing a sharper and clearer image compared to spherical mirrors.
Therefore, the correct answer is C. only defective spherical mirrors, as they are the ones that do not properly focus the light rays at the focal point.

Will the velocity of a book change as it moves across the surface with friction
Friction force is a force that opposes relative motion of two bodies that have contacting surfaces
Yes, the velocity of the book will change as it moves across the surface with friction
Reason:
According to Newton's first law of motion, a body will remain at rest or move with a constant speed in a straight line unless acted on by a force
Friction force, f = Normal reaction, N × Coefficient of friction, μ
A surface with friction has frictional force that opposes the relative motion of an object in surface contact across it
When an object such as a book moves across a surface with friction, the friction force acts on the book having a velocity, opposing the motion of the book, therefore, slowing down the book
Therefore, the velocity of the will change (reduce) as it moves across the surface with friction
