A skier at the bottom of a hill has 900J of kinetic energy. After sliding a ways along the flat, the kinetic energy is 300J. How much energy was lost due to friction?
Answer:
600 J
Explanation:
900 j = 300j = 600 j lost due to friction
Energy lost due to friction is 600 J.
The kinetic energy before and after friction is given as 900J and 300J.
What is friction?The force that resists the sliding or rolling over one object with another is called friction. The energy which possess in virtue of being in motion is said to be Kinetic Energy.
f = μN
Energy lost = 900J - 300J
= 600J

Group of answer choices True False
Increasing the resistance of a variable resistor wired in series with a light bulb will not affect the voltage drop on the bulb [FALSE].
Series circuitA series circuit is a type of circuit arrangement, where the same current flows in each resistor of the circuit. Also Different voltage flow in each resistor of the circuit.
The total voltage drop in a series circuit is given as;
V = IR₁ + IR₂ + IR₃ + ----
V = I(R₁ + R₂ + R₃)
From the above equation, increase in the number of resistance, increases the voltage drop.

During a solar eclipse as seen from Earth, the moon will be at the position Z.
What is meant by solar eclipse ?When the Moon moves in front of the Sun, obstructing the Sun's view for a small portion of the Earth either completely or partially, this is known as a solar eclipse.
Here,
When the Moon is in its new moon phase, when its orbital plane is closest to that of the Earth's, and during eclipse season, such an alignment takes place roughly every six months. The Sun's disc is completely covered by the Moon during a total eclipse. The Sun is only partially covered by annular and partial eclipses. A solar eclipse can only be seen from a relatively restricted area of the earth, in contrast to a lunar eclipse, which can be seen from anyplace on the night side of Earth.
The Moon is parallel to the line connecting the Earth and the Sun at its first and final quarters. Only one-half of the Moon is visible to us as being illuminated by the Sun; the other one-half is hidden in shadow.
Hence,
During a solar eclipse as seen from Earth, the moon will be at the position Z.

it the satellite is put into a new circular orbit of a smaller radius, how will the Fo and the speed of the satellite change, if at all?
A Both gravitational force and speed will decrease
OB. The gravitational force will decrease and speed will increase
O c The gravitational force will increase and speed will decrease
OD. Both gravitational force and speed will increase
OD
Explanation:
both gravitational force and speed will increase
The gravitational force will increase and speed will decrease. So, the correct option is c.
What is meant by gravitational force ?Any two objects in the universe are attracted towards each other by the gravitational force, regardless of whether their masses are equal or not.
Here,
Newton's universal law of gravitation states that the force of attraction between any two bodies is inversely proportional to the square of the distance between them and directly proportional to the product of their masses.
So, the gravitational force of the satellite,
F ∝ 1/R²
where R is the radius of the circular orbit.
The equation for speed of the satellite is given by,
v = √Rg
where g is the acceleration due to gravity.
So, the speed is directly proportional to the square root of the radius of the orbit.
v ∝ √R
Therefore, as a result of the decrease in the radius of the orbit, the gravitational force of the satellite will increase, and its speed will decrease.
Hence,
The gravitational force will increase and speed will decrease.

What are the benefits, mechanisms and limitations of explaining, modelling and describing the material cosmos?
The study of the cosmos provides scientists with a knowledge of the material universe although limited due to lack accurate tools and equipments for the study of the cosmos.
What is the cosmos?The cosmos refers to the entire universe including the things found in them.
Understanding and explaining the universe has as always been of interest to humans both ancient and model.
Humans in ancient times earlier modelled the earth to be the centre of the universe known as the geocentric model.
A heliocentric model was proposed later to replace the geocentric model.
Both ways of modelling was limited as cosmologists did not have the tools to accurately observe outer space.
Today, advances in technology has provided powerful tool to ore accurately model the cosmos.

A 82.9 kg weight-watcher wishes to climb a mountain to work off the equivalent of a large piece of chocolate cake rated at 670 (food) calories. How high must the person climb? The acceleration due to gravity is 9.8 m/s2 and 1 food calorie is 10^3 calories.
The weight watcher must climb : 3.45 km to work off the equivalent of a large piece of chocolate cake rated at 670 calories.
Determine how high the weight-watcher must climbFirst step : convert the energy to joules
670 calories to Joules
E = 670 * 10³ * 4.184
= 2803280 J
Next step : Equate energy to gravitational potential energy
2803280 J = mgh
2803280 = 82.9 * 9.8 * h
Therefore :
h = 2803280 / ( 812.42 )
= 3451 m = 3.45 Km
Hence we can conclude that The weight watcher must climb : 3.45 km
