If a 2,300 kg car is accelerating at 16 m/s^2, what is the force it is producing?
Answers
Force = (mass) x (acceleration)
In order to acceleratethe car at that rate, a force of
(2,300 kg) x (16 m/s²) = 36,800 newtons
(about 8,270 pounds ... 4.14 tons !)
has to be coming from somewhere ... presumably from the straining,
screaming, smoking engine under the hood.
The force it might apply to an object it runs into will depend on the
shape and composition of that object.

Answer:
0.8684 atm
Explanation:
Using combined gas equation,
PV / T = k
P1*V1 / T1 = P2*V2 / T2
P1 = 1.10 atm
P2 = ?
V1 = 2.5L
V2 = 3.9L
T1 = 298k
T2 = 367k
P1*V1 / T1 = P2*V2 / T2
Making P2 the subject of formula;
P2 = P1*V1*T2 / V2*T1
P2 = 1.1*2.5*367 / 3.9*298
P2 = 1009.25 / 1162.2
P2 = 0.8684 atm
Here you go
This problem can be solved using one of the different gas laws, which is shown below:
PV/T
Given:
P1 = 1.1 atm
V1 = 2.5 L
T1 = 298 K
P2 = ?
V2 = 3.9 L
T2 = 367 K
Substituting the given:
P1V1/T1 = P2V2/T2
(1.1 * 2.5)/298 = (P2 * 3.9)/367
P2 = 0.868 atm

The correct answer to the question is C) 400 J.
CALCULATION:
As per the question, the force applied on the block F = 40 N.
The distance travelled by the block S = 10 m.
We are asked to calculate the work done by the block.
The work done by a body under a force F is calculated as -
Work done W =
=
Here, is the angle between force and displacement.
If , then work done W =
= FS. [ cos0 = 1]
Hence, the work done by the block W = FS
= 40 N × 10 m
= 400 Joule. [ans]
Here, Joule is the unit of work.
Hence, the work done by the block s 400 Joule.

The identity of the element is determined by the number of protons
in the nucleus of each atom.
If two atoms have the same number of protons in their nucleii
(nucleuses) but different numbers of neutrons, then they're both
atoms of the same element, but their atomic masses are different,
and they're called isotopes of the element.
In the picture, atoms 'A' and 'B' each have 3 protons in the nucleus,
so they're both atoms of Lithium. But the number of neutrons is
different, so 'A' and 'B' are different isotopes of Lithium.
Also in the picture, atoms 'C' and 'D' each have 4 protons in the
nucleus, so they're both atoms of Beryllium. But the number of
neutrons is different, so 'C' and 'D' are different isotopes of Beryllium.
