The rover Spirit is a robotic probe that NASA has placed on Mars. The
gravitational attraction of Mars is approximately 62% less than that of Earth. Compared to its measurements on Earth, on Mars the probe has
-the same weight and the same mass.
-a larger weight, but smaller mass.
-a smaller mass and larger weight.
- a smaller weight and the same mass.
Answers
Answer:
D) a smaller weight and the same mass is the answer
Explanation:
The rover Spirit is having a smaller weight and the same mass on Mars because of the Strength of Gravity on Mars
The Strength of Gravity depends on the mass of the object as gravity is directly proportional to mass which means more mass more gravity and vice versa
Another example of an object-to-gravity relation is SUN as Sun is the biggest object in the solar system it has the greatest Gravitational pull which is keeping the planets in the solar system intact and in their paths

For this assignment, you will research how to design and build a solar cooker. Search reliable online sites
for “solar cookers.” After getting the materials you need from your teacher, you will present your initial
design as a drawing or illustration. You will then build your device and test its efficiency by warming up a
hot dog until it reaches an internal temperature of 165°F, recording how long it took you to reach this
temperature. Based on your tests, you will make recommendations on how to improve the design of your
solar cooker, and then present your final design and the logic that supports it in a lab report. Your lab
report should include a title, a list of materials that you used to build your solar cooker, a drawing of your
initial design, observations from your experimental tests, recommendations for a final design based on
what you know about radiation, a drawing of your final design, and the results of the efficiency test. To
help you write your lab report, there is a Student Worksheet on the last few pages of this document.

You will need a magnifying glass and a small piece of scrap paper for this demonstration.
a. Go outside on a sunny day and put the piece of paper on a patch of asphalt, concrete, or a large flat rock. Make sure there is no other combustible material or debris in the vicinity.
b. Hold the magnifying glass so it is close to the paper, with rays of sunlight shining through it. Move the magnifying glass side to side and close or away from the paper until the most concentrated ray of light is shining on the paper. This is the focal point for that magnifying glass.
c. Measure the distance between the focal point and magnifying glass. This is the focal length for that magnifying glass. (Be careful; if you hold the magnifying glass in that place for long enough, the paper will catch fire. Do not ever do this on your skin or clothing, as it can cause serious burns.)

Power is the rate at which work is done. James Watt is a famous engineer and inventor who developed the steam engine.
Who is James Watt?He improved the efficiency of the engine by adding a separate condenser, which reduced the amount of fuel needed. In his honor, the watt was named after him as the unit of power.

Answers
Answer:Gravity is the force among the options listed that has not directly changed Earth's surface.
Explanation:
Gravity is a fundamental force that acts on all objects with mass, including the Earth itself, but it does not cause changes or modifications to the Earth's surface features. Instead, gravity influences the movement of materials and the shape of the Earth's surface by exerting a pulling force on objects. On the other hand, folding, erosion, and weathering are all processes that directly contribute to shaping

During a hockey game, the puck slid from the center line directly to the goal line in 1.5 seconds. The center line is 27 meters from the goal line. As the puck slid, it was chased by a hockey player skating at 9.5 meters per second. What was the puck's velocity?
Answers
Answer: The pucks velocity was 18 meters per second.
Explanation: First I divided 27 by 3 because of the 1.5 seconds and the i multiplied my answer by 2 and got that it traveled 18 meters in 1 second.
During a hockey game, the puck slid from the center line directly to the goal line in 1.5 seconds. The center line is 27 meters from the goal line. As the puck slid, it was chased by a hockey player skating at 9.5 meters per second. And the puck's velocity is 18 m/s.
What is Average velocity?
Average velocity can be defined as the average rate of change of displacement with respect to time. Average velocity is a measure for distance traveled in a given time.
We can calculate the average velocity by the rule
v = s/t (m/s)
where s is the displacement and t is the time
Mathematically,
speed = distance/ time
The puck traveled a distance of 27 m in 1.5 seconds
The speed of the puck is thus;
27/1.5 = 18 m/s
Thus, the puck's velocity can be calculated as 18 m/s.

If you push a book against a wall hard enough, it will not slide down even though gravity is pulling it. Use what you know about Newton’s laws of motion to explain why the book is not falling. (giving away brainliest!)
Answers
f = coefficient of friction (u) X Normal reaction exerted by the surface (N)
So, f = u X N.
Now 'u' is a constant for given surfaces in contact ( keep in mind that it depends on both the surfaces that are in contact with each other, here wall and the book that you are pressing)
Now, Normal reaction is equal and opposite to the force exerted by an external force on the surface, PERPENDICUAL TO THE SURFACE ( or the perpendicular component of the external force). The external force exerted on the surface which is vertical to it, in this case, is equal to the force that you are applying while you are holding/pressing the book against the wall.
So, at any point of time, frictional force = u X (Force you are applying on the surface, via the book)
Or, f = u X F, where,
f = frictional force,
u = coefficient of friction, and
F = Perpendicular component of the force exerted by you on the book towards the surface.
Now direction of f -
Frictional force always act parallel to the surface and in opposite direction to the direction of motion.
In absence of friction, book will fall down, because of gravity acting on it. So friction will try to act in the opposite direction of this motion. So, upwards in this case.
If let's say you have a metal object placed between magnets, which is applying more force on it than gravity, in upwards direction; and you try to press it against the wall, the motion of object will be upwards, so friction will then act downwards.
Friction always opposes the direction of motion in which the object would have moved because of RESULTANT FORCE on it in absence of friction.
Takeaways in English (or, common observation) -
1) Harder you press the book against the wall, harder it will be for a person to move the book on the surface of the wall, while you are pressing it. Because of higher friction.
2) The more you move the book on the wall, while keep on pressing it, warmer the surface of the book which is in contact with wall will be. Because if more energy is dissipated per second to overcome friction, which gets converted to heat energy.
2.1) Harder you press, book will heat up faster.
3) Harder you press the book against the wall, lesser chance are that it will fall down. Because more frictional force is now acting on it to hold it against gravity.
4) Heavier the book, more frictional force is needed to hold it from falling, and that is why you have to press it harder to hold Heavier books.
5) That is all I can think of right now. Try applying this concept in things you see around.
