A ball rolling down a ramp accelerates from 0 m/s to 40 m/s in 10 seconds. What is its acceleration?

Answer:

gas has the most energy! hope that helps :D

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.

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 %.

Answer:

it is based on an observation of a natural phenomenon

Explanation:

Answer:

diplacement 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.

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.

-- From 1 to 3 seconds, the acceleration is 2.5 m/s².  (It changes suddenly at 3 seconds.)

-- At 2 seconds, the speed is 2.5 m/s .

-- At 2 seconds, the position is 1.25 meters.

I don't know where you got this graph, but you have to be very very careful when you try to read it.  The Y-axis is not at time=0.  It's at time=1.  And all the whole-number seconds are between the blue lines.

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

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

Answer

you need to give the speed (velocity)

Explanation:

with the speed given you input that into d= v*t

you know one hour or 60 minutes or 3600 seconds which are all equivalent and you can use any as the units need to be the same to do any equation and multiply that by the speed that you have already

Explanation:

Answer:

x = 10

Explanation:

215 = 25x – 35

215 + 35 = 25x

250 = 25x

x = 250 / 25

x = 10

Weight is the the force of gravity on an object.

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.

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
