Weight is the the force of gravity on an object.
What is weight?Weight in physics is the force on an object due to the gravitational attraction between it and the Earth (or whatever astronomical object it is primarily influenced by).
Weight is often confused with mass, however, weight is a force measured in Newtons (N) rather than in kilograms like mass.
The weight of an object is subjective to its location and it can be calculated from the mass by multiplying the mass by the acceleration due to gravity of the planet it is located.

If an element's atomic mass and atomic number are known, what else can be determined? Give an example to demonstrate your understanding
Answer:
Explanation:
If an elements atomic mass and number are known you can also determine the number of protons and neutrons it has. You can also determine where it is on the periodic table. For example, if a element had a atomic mass of 10 then it would be higher up on the table then one with a mass of 20. Btw I do apex too.

A cubic meter (m³) is ____________a cubic centimeter (cm³).
(A) larger than
(B) different from
(C) smaller than
(D) equal to
Your answer is D: equal to
Answer:
Larger than
Explanation:
cause if you look it up it says ¨1 Cubic meter (m3) is equal to 1000000 cubic centimeters (cm3). To convert cubic meters to cubic centimeters, multiply the cubic meter value by 1000000.¨ which mean you need one million cubic centermeters to make one cubic meter. so dont trust the other answer i dont think
HELPPPPPPPP PLSSSSSSSS A car moves with constant velocity along a straight road. Its position is x1 = 0 m at t1 = 0 s and is x2 = 66 m at t2 = 6.0 s . Answer the following by considering ratios, without computing the car's velocity.\ 1.What will be its position at t = 24 s ? 2.What is the car's position at t = 3.0 s ?
Answer:
Explanation:
6.2 miles
Answer: 1. 264, 2.33
Explanation: Explanation: 66m= 6s so, to find the position at 3s you just need to take 66/2 = 33m cause 3 is half of 6. & for 2 you will take 66x4= 264m cause it took 4s multiply by the original 6s to get 24s. Answer: 1 is 264m & 2 is 33m.

A student measured the specific heat of water to be 4.29 J/g.Co. The
literature value of the specific heat of water is 4.18 J/g.Co. What was the
student's percent error? *
A) .0256%
B) 2.56%
C) 2.63%
D) .0263%
Answer:
2.63 %.
Explanation:
Given that,
The calculated value of the specific heat of water is 4.29 J/g.C
Original value of specific heat of water is 4.18 J/g.C.
We need to find the student's percent error. The percentage error in any quantity is given by :
[tex]P=\dfrac{|\text{original value-calculated value}|}{\text{original value}}\times 100\\\\P=\dfrac{4.29-4.18}{4.18}\times 100\\\\P=2.63\%[/tex]
So, the student's percent error is 2.63 %.

Lucifer is in a train traveling initially at 5.48 m/s west when she begins to accelerate west at the rate of 0.892 m/s/s for a time of 6.90 s. What is her velocity at the end of the acceleration?
Recall that
[tex]v_f=v_i+at[/tex]
which follows from the definition for average acceleration. So Lucifer has a final velocity of
[tex]5.48\dfrac{\rm m}{\rm s}+\left(0.892\dfrac{\rm m}{\mathrm s^2}\right)(6.90\,\mathrm s)\approx\boxed{11.6\dfrac{\rm m}{\rm s}}[/tex]

Explanation:
12) A 26 kg chunk of ice is slid west across the frictionless surface of a frozen lake at 1.7 m/s . The chunk of ice collides with another chunk of ice, which is stationary and has a mass of 12 kg. The two chunks slide together as a single piece after the collision Calculate the final velocity of the combined ice chunks Show your work including the equation(s), values for the variables, and units
Answer:
1.16 m/s
Explanation:
Mass of first ice; m1 = 26 kg
Mass of second ice; m2 = 12 kg
Velocity of first ice; v1 = 1.7 m/s
Velocity of second ice; v2 = 0 m/s
From inelastic collision, the formula we will use is;
m1•v1 + m2•v2 = (m1 + m2)v'
Where v' is the final velocity of the combined ice chunks
Plugging in the relevant values gives;
(26 × 1.7) + (12 × 0) = (26 + 12)v'
44.2 = 38v'
v' = 44.2/38
v' ≈ 1.16 m/s

1. If you move 4 meters north and move 2 meters south what is the distance and the displacement?
2. If you move 2 meters east and move 4 meters west what is the distance and the displacement?
Please help!!It’ll be greatly appreciated
Answer:
distance will be 6diplacement will be 2
2. distance will be 6
displacement will be 2
The distance if we move 4 meters north and 4 meters south is 6 meters whereas, the displacement is 2 m. The same for the movement of 2 meters east and 4 meters west.
What is distance ?Distance is a physical quantity that measures how far we travelled from rest. It is the total length of the ways we moved. Distance is a scalar quantity. Displacement is a vector quantity showing the distance magnitude as well the direction.
If a person moves equal distances in opposite directions, then the displacement will cancel each other as in the case of force and the net displacement is zero.
Here, if move 4 m north and 2 meters south, the total distance is their sum , i.e., 6 meters. But the displacement for the opposite directions cancel in magnitude and the net displacement is 4-2 = 2 meters.
The same is applied for east and west movement. Hence, the distance is 6 m and displacement is 2 m.

Answer:
30 m/s
Explanation:
Given:
v₀ = 0 m/s
a = 3.0 m/s²
t = 10 s
Find: v
v = at + v₀
v = (3.0 m/s²) (10 s) + 0 m/s
v = 30 m/s
