A baboon pushes a 3.1 kg stone with 150 j of kinetic energy.
What is the stone’s speed?
The speed of the stone is 9.8 m/s
Explanation:
Given data,
Mass - 3 kg K.E 150-J
We have to find the speed of the stone
We have the formula
K.E =1/2 m× v ²
Rewrite the equation as
v= √ 2×K.E/m
v= √2 ×150/ 3.1
v=9.83 m/s
The speed of the stone is 9.8 m/s
A baboon pushes a 3.1 kg stone with 150 J of kinetic energy.
What is the stone’s speed?
Answer: 9.83
A 25 kg rock falls for 2.7 seconds. How many meters tall was the
building?
Assume no air resistance, answer using two place values
Answer:
35.72 m
Explanation:
Given:
v₀ = 0 m/s
a = 9.8 m/s²
t = 2.7 s
Find: Δx
Δx = v₀ t + ½ at²
Δx = (0 m/s) (2.7 s) + ½ (9.8 m/s²) (2.7 s)²
Δx = 35.72 m
A waitperson carrying a tray with a platter on it tips the tray at an angle of 12° below the horizontal. If the gravitational force on the platter is 5.0 N, what is the magnitude of the force parallel to the tray that tends to cause the platter to slide down the tray? (Disregard friction.)
a.
0.42 N
c.
4.9 N
b.
1.0 N
d.
5.0 N
Answer:
The answer is 1.0 N
Explanation:
inclination of tray=12^{\circ}
gravitational Force=5 N
Now this gravitational force has two component i.e.
5\sin \theta is parallel to the tray =1.039 N
5\cos \theta is perpendicular to the tray =4.890 N
The magnitude of the force parallel to the tray that tends to cause the platter to slide down is approximately 1.0 N.
Explanation:To determine the magnitude of the force parallel to the tray that tends to cause the platter to slide down, we need to find the component of the gravitational force that acts parallel to the tray. This can be done using trigonometry.
The component of the gravitational force parallel to the tray is given by the formula:
F_parallel = F_gravity * sin(theta)
Plugging in the given values:
F_parallel = 5.0 N * sin(12°)
Solving this equation, we find that the magnitude of the force parallel to the tray is approximately 1.0 N (option b).

Which of the following is a field force
Answer:
magnetic, gravity, electrostatic all are field forces
Explanation:
help this help! :)
Among the options provided, both magnetic force and electric force are examples of field forces. Thus, option 1 and 2 is correct.
Explanation:Magnetic force arises due to the interaction between moving charges or magnetic dipoles in a magnetic field. It is responsible for phenomena such as the attraction or repulsion between magnets, the operation of electric motors, and the behavior of charged particles moving through magnetic fields. Magnetic fields are produced by moving charges or currents, creating a force that acts on other moving charges within the field.
Electric force, similarly, arises from the interaction between charged particles within an electric field. This force is responsible for the attraction or repulsion between charged objects, the operation of devices like capacitors, and the behavior of charged particles in electric fields. Electric fields are created by static charges or changing magnetic fields, exerting a force on other charged particles within the field.
Both magnetic and electric forces are examples of field forces because they are transmitted through fields (magnetic or electric fields, respectively) and act at a distance without direct contact between the interacting objects. Conversely, normal force and gravitational force are contact forces, as they require physical contact between objects to manifest.

How many electrons are there in the third energy level?
Answer:
18 electrons
Explanation:
The third energy level of an atom can hold up to 18 electrons, spread across the 3s, 3p, and 3d subshells.
Explanation:The third energy level of an atom can hold a maximum of 18 electrons. This is due to the existence of three possible subshells in this energy level, namely 3s, 3p, and 3d. As per the electron configuration rule, an s subshell can hold 2 electrons, a p subshell can hold 6, and a d subshell can hold 10. Consequently, the third energy level, which comprises these three subshells, can collectively accommodate up to 18 electrons (2 from the s subshell, 6 from the p subshell, and 10 from the d subshell). Keep in mind, however, that the complete filling of all these subshells in the third energy level is not applicable to all elements, but rather depends on the specific electron configuration of the atom.Learn more about third energy level here:https://brainly.com/question/21326300

In which situation will the lowest resistance occur?
A. thick wire and high temperature
B. thin wire and high temperature
C.thick wire and cold temperature
D.thin wire and low temperature
C. Thick wire and cold temperature.
Explanation:
The resistance of a wire is given by: R = (ρL)/A
where ρ is the resistivity of the material, L is the length of the wire, A is the cross-sectional area of the wire.
From the formula, we see that the thicker the wire, the larger A, therefore the smaller the resistivity. so, a thick wire will have lower resistivity.
Moreover, the resistance of a wire increases with the temperature. In fact, high temperatures mean more motion of the atoms/electrons inside the wire, so more resistance to the flow of current through it. Therefore, colder temperature means lower resistance.
So, the correct option is thick wire and cold temperature.
Answer:
C. Thick wire and cold temperature.

What’s is inductive reasoning?
Answer:
got this on google and got it right
Explanation:
An example of inductive logic is, "The coin I pulled from the bag is a penny. ... Even if all of the premises are true in a statement, inductive reasoning allows for the conclusion to be false. Here's an example: "Harold is a grandfather. Harold is bald.
Inductive reasoning is when someone observes data, recognizes patterns within these observations, and then draws a conclusion on these observations that they found.
Let's look at an example.
A 12-oz. coke bottle exploded after an hour in the freezer.
A second 12-oz. coke bottle exploded after an hour in the freezer.
The reasoning that was used here was inductive reasoning.
Although we might want to test a few more 12-oz. coke bottles, we can tentatively conclude that all 12-oz. coke bottles will explode after an hour in the freezer.
Since were using oneservations and recognizing patterns to draw a
conclusion, our conclusion is based on inductive reasoning.

Explanation:
Answer:

As the car moves from point A , to point B, and finally to point C, the total energy of the car
A. decreases from point A to point B, then increases from point B to point C
B. increases from point A to point B, then decreases from point B to point C
C. stays the same, but is converted between potential and kinetic energy
D. is lost between points B and C
Answer: C
Explanation:
Energy stays the same, but there’s more kinetic energy the less it moves and mor kinetic energy the more it moves
The conservation of energy allows us to find the correct answer for how the change in mechanical energy is:
C. stays the same, but is converted between potential and kinetic energy.
The mechanical energy of bodies is the sum of the kinetic energy due to motion and the potential energies due to the configuration of the system.
If there is not friction in the system, that is, there are no dissipative forces, the mechanical energy must be conserved at all points, this is one of the important conservation laws of physics.
When applying this theorem to the case of the car moving, the energy is converted from potential to kinetic, on the path from A to B and is transformed from kinetic to potential on the path from B to C, but the total value of the mechanical energy remains constant.
Let's analyze the different claims:
A. False. The stable energy conservation theorem that must be constant at all points.
B. False. Must be constant.
C. True. According to the analysis, the mechanical energy is constant and transforms between potential and kinetic.
D. False. As there is no friction, the energy is not lost.
In conclusion using the conservation of energy we can find the correct answer for the transformation of mechanical energy is:
C. Stays the same, but is converted between potential and kinetic energy.
