how far will an automobile move if 168000 j of work is created by 2000 n of force
Answers
Answer:
Distance = 84 meters
Explanation:
Given the following data;
Work done = 168,000 Joules
Force = 2,000 Newton
To find the distance covered by the automobile, we would use the formula;
[tex] Workdone = force * distance [/tex]
Substituting into the formula, we have;
[tex] 168000 = 2000 * distance [/tex]
[tex] Distance = \frac {168000}{2000} [/tex]
Distance = 84 meters

If a machine increases force it must apply the force over a long distance? True or false
Answers
Answer: The machine must apply the force over a shorter distance. That's because a machine doesn't change the amount of work and work equals force times distance. Therefore, if force increases, distance must decrease
FALSE

A 30.0 kg rock falls from a 35.0 m cliff. What is the kinetic and potential energy when the rock has fallen 12.0 m?
Answers
Answer:
When the rock has fallen 12.0 m;
The kinetic energy of the rock is approximately 3,531.6 J
The potential energy of the rock is approximately 6,768.9 J
Explanation:
The question relates to the characteristic constant total mechanical energy of a body
The mass of the rock that falls, m = 30.0 kg
The height of the cliff from which the rock falls, h₁ = 35.0 m
The required information = The kinetic and potential energy when the rock has falling 12.0 m
The kinetic energy is given by the formula, K.E. = 1/2×m×v²
The potential energy is given by the formula, P.E. = m·g·h
Where;
g = The acceleration due to gravity ≈ 9.81 m/s²
The velocity of the rock after falling through a given height, h is given by the formula, v² = 2·g·Δh
The total mechanical energy of the rock, M.E. = K.E. + P.E. = Constant
At the height of the cliff before falling, Δh =0, therefore v₁ = 0, therefore, K.E. = 1/2×m×v₁² = 0 J
The potential energy at the cliff before the rock begins to fall, P.E. is goven as follows;
P.E. = 30.0 kg × 35.0 m × 9.81 m/s² = 10,300.5 J
At the top of the cliff, M.E. = K.E. + P.E. = 0 J+ 10,300.5 J = 10,300.5 J
∴ M.E. = 10,300.5 J
When the rock has fallen, 12.0 m, Δh = 12.0 m, the speed of the rock, v₂, is given as follows;
v₂² = 2 × 9.81 m/s² × 12.0 m = 235.44 m²/s²
v₂ = √(235.44 m²/s²) ≈ 15.344 m/s
∴ When the rock has fallen 12.0 m, K.E., is given as follows;
K.E. = 1/2×m×v₂²
K.E. = 1/2 × 30.0 kg × 235.44 m²/s² = 3,531.6 J
When the rock has fallen 12.0 m the kinetic energy, K.E. = 3,531.6 J
When the rock has fallen 12.0 m, M.E. = P.E. + K.E.
M.E. = Constant = 10,300.5 J
K.E. = 3,531.6 J
∴ 10,300.5 J = P.E. + 3,531.6 J
P.E. = 10,300.5 J - 3,531.6 J = 6,768.9 J
∴ When the rock has fallen 12.0 m, the potential energy, P.E. = 6,768.9 J.

The main reason for using light years, however, is because the distances we deal with in space are immense. If we stick to miles or kilometers we quickly run into unwieldy numbers just measuring the distance to the nearest star: a dim red dwarf called Proxima Centauri that sits a mere 24,000,000,000,000 miles away!

Scott is making a chart to show the difference between chemical reactions and nuclear reactions. Which part of his chart is incorrect? Chemical Reaction Nuclear Reaction Line 1 Happens in the nucleus of atoms Happens between atoms Line 2 Forms new compounds Forms new atoms and radioactive particles Line 3 Involves small amounts of energy Involves large amounts of energy
Answers
Answer:
The incorrect part of the chart is;
Line 1
Chemical [tex]{}[/tex] Reaction [tex]{}[/tex] Nuclear Reaction
Line 1 Happens in the nucleus of atoms [tex]{}[/tex] Happens between atoms
Explanation:
The given chart can be presented as follows;
Chemical Reaction [tex]{}[/tex] Nuclear Reaction
1. Happens in the nucleus of atoms [tex]{}[/tex] Happens Between atoms
2. Forms new compounds [tex]{}[/tex] Forms new atoms
3. Involves small amounts of energy [tex]{}[/tex] Involves large amounts of energy
From the above chart, line 1 is incorrect because a chemical reaction happens between the valence electrons of the reacting atoms while a nuclear reaction is the reaction that takes place between the nucleus of two or more atoms or the nucleus of an atom and a subatomic particle to produce one or more than new nuclide of a new atom with a change in the mass of the nucleus being represented by the large amount of energy in the reaction. Therefore, a nuclear reaction takes place in the nucleus of an atom, forms new atoms and involves large amounts of energy
The correct arrangement is presented as follows;
Chemical Reaction [tex]{}[/tex] Nuclear Reaction
1. Happens Between atoms [tex]{}[/tex] Happens in the nucleus of atoms
