Answer:
The correct option is (d).
Explanation:
The energy a particle has because of its charge and its position relative to another particle is called thermal energy. It is the energy that comes from heat. This is generated by the movement of the particles in an object.Thermal energy is the energy an object or system has due to the movement of particles within.Hence, the correct option is (d).
The thermal energy is related to the kinetic energy of atoms, ions, and molecules.
What is thermal energy?The thermal energy of any material is defines as the increase in the internal energy of the material.
When ever heat is given to the material, the atoms and the molecules in the material gains energy and moves with a kinetic energy.
The increase in kinetic energy allows the atoms and the molecules to move with higher velocities in the material, and they collide with each other, thus the temperature of the material increases.
Thus the thermal energy is related to the kinetic energy of atoms, ions, and molecules.

Answer:
temperature is the average kinetic energy of the particles of matter. the hotter something is the more kinetic energy it has.
Explanation:
Air from a metal can is removed so the pressure in the can decreases to 70000Pa, the can is then sealed. The pressure from outside the can is atmospheric pressure which is 100kPa. The area of one side of the can is 1.5m2, find the resultant force on this side of the can.
Answer:
F = 45 KN = 45000 N
Explanation:
Considering the downward direction as the positive direction:
[tex]P = P_1 - P_2[/tex]
where,
P = Resultant Pressure = ?
P₁ = Atmospheric Pressure = 100 KPa
P₂ = Pressure inside the can = 70000 Pa = 70 KPa
Therefore,
[tex]P = 100\ KPa - 70\ KPa\\P = 30\ KPa[/tex]
Now the resultant force will be given as:
[tex]F = PA[/tex]
where,
F = resultant force = ?
A = Area of side of can = 1.5 m²
Therefore,
[tex]F = (30\ KPa)(1.5\ m^2)\\[/tex]
F = 45 KN

How does friction affect the output of machines?
Answer:
In a machine, friction reduces the mechanical advantage, or the ratio of output to input: an automobile, for instance, uses one-quarter of its energy on reducing friction. Yet, it is also friction in the tires that allows the car to stay on the road, and friction in the clutch that makes it possible to drive at all

A golfer wants his shot to land
122 m away on flat ground.
His club launches balls at a 55.0°
angle. How fast should
the ball leave the club?
(Unit = m/s)
Answer:
35.67 m/s
Explanation:
Applying the formular for range,
R = u²sin2∅/g....................... Equation 1
Where R = Range, u = Initial Velocity, ∅ = angle of launch, g = acceleration due to gravity
make u the subject of the equation
u = √(Rg/sin2∅)............. Equation 2
Given: R = 122 m, g = 9.8 m/s², ∅ = 55°
Substitute these values into equation 2
u = √[(122×9.8)/(sin(2×55))]
u = √(1195.6/sin110)
u = √(1272.33)
u = 35.67 m/s

what is the velocity of a car that went a distance of 400ft in 25 seconds
Speed = (distance covered) / (time to cover the distance)
Speed = (400 ft) / (25 seconds)
Speed = 16 ft/sec
That's the car's speed.
We don't have enough information to state its velocity.

A 1.50-kg cart rolls along a horizontal table at a constant speed of 1.70 m/s. A ball of soft putty is dropped from a stationary hand onto the cart as it passes underneath. If the speed of the cart is reduced to 1.53 m/s, calculate the mass of the ball of putty. This collision is completely inelastic
Answer:
0.17 kg
Explanation:
mc = mass of cart
mb = mass of ball
vc = speed of cart before collision
vb = speed of ball before collision (vb = 0)
v' = speed of cart and ball after collision
mc . vc + mb . vb = (mc + mb) . v'
(1.5)(1.7) + mb(0) = (1.5 + mb) . 1.53
2.55 + 0 = (1.5 + mb) . 1.53
2.55/1.53 = 1.5 + mb
5/3 = 3/2 + mb ( I change it to fraction)
mb = 5/3 - 3/2 = 10/6 - 9/6 = 1/6 kg
mb = 1/6 kg = 0.17 kg

Koby placed ½ teaspoon of baking soda into each of two identical glasses. He noticed the baking soda was lumpy, so he used a fork to break up the lumps. Why is it important to break up the lumps?
Answer:
because the lumps are just baking soda covered with whatever watery substance you used.
Explanation:
so pretty much inside the lumps is just a bunch of baking soda

Kamal, Kamala, Krishna invert a sum of RS= 30,000 on a business in the ratio 2 : 3 : 5. Find the each of their investment.
Answer:
Explanation:
Kamal, Kamala, Krishna invert in the ratio 2 : 3 : 5.
As 2+3+5 =10, their respective share is 2/10, 3/10 and 5/10.
Sum of investment = 30000Rs
Kamal's investment = 30000 * 2/10 = 6,000 Rs
Kamala's investment = 30000 * 3/10 = 9,000 Rs
Krishna's investment = 30000 * 5/10 = 15,000 Rs
why is fluorine more chemically reactive than
nitrogen?
Answer:
Nitrogen has Electronic configuration 1s2 2s2 2p3. Fluorine has Electronic configuration 1s2 2s2 2p5 i.e. nitrogen has half filled p subshell that makes it more stable than fluorine and fluorine requires only 1 electron to complete it's octet to get stable..Therefore Fluorine is more reactive than Nitrogen.

Are humans evolving? What will humans look like in 100,000 years in the future or longer?
Answer:
yes
Explanation:
explain why the rate of diffusion of a gas decreases with decrease in temperature
Temperature: Higher temperatures increase the energy and therefore the movement of the molecules, increasing the rate of diffusion. Lower temperatures decrease the energy of the molecules, thus decreasing the rate of diffusion. Solvent density: As the density of a solvent increases, the rate of diffusion decreases.
A student of mass 45kg, who is undergoing National Service training, takes 6s to climb a flight of stairs that had 36 steps. If each step is 16cm high, what is the power of the student?
Answer:
Approximately [tex]4.2 \times 10^{2}\; \rm W[/tex] on average in the vertical direction (assuming that [tex]g = 9.8\; \rm N \cdot kg^{-1}[/tex].)
Explanation:
Vertical displacement of this student in [tex]6\; \rm s[/tex]: [tex]36 \times 16\; \rm cm = 36 \times (0.16\; \rm m) = 5.76\; \rm m[/tex].
Average vertical velocity of this student: [tex]v = \displaystyle \frac{5.76\; \rm m}{6\; \rm s} = 0.96\; \rm m \cdot s^{-1}[/tex].
The average vertical force that this student exerts on the ground would be equal to the weight of this student:
[tex]F = W = m \cdot g = 45\; \rm kg \times 9.8\; \rm N \cdot kg^{-1} = 441\; \rm N[/tex].
The average power of this student in the vertical direction is equal to the product of the force and velocity of this student in that direction:
[tex]P = F \cdot v = 441\; \rm N \times 0.96\; \rm m \cdot s^{-1} \approx 4.2\times 10^{2}\; \rm W[/tex].

A sphere is released into the atmosphere where air resistance is present. As it falls it loses 7J of potential energy. How much kinetic energy did it gain?
Answer:
7 J
Explanation:
Given that,
A sphere is released into the atmosphere where air resistance is present.
The lose in energy is equal to 7 J
We need to find the gain in its kinetic energy.
We know that, as per the law of conservation of energy,
Loss in potential energy = gain in kinetic energy
⇒
Gain in kinetic energy = 7 J
Hence, the gain in kinetic energy is 7 J.
