Answer:
b is the answer the third law
Explanation:
B because Newton's second law, which states that the force F acting on a body is equal to the mass m of the body multiplied by the acceleration a of its centre of mass, F = ma, is the basic equation of motion in classical mechanics.
A scientist is designing a device that will mimic Earth's atmosphere by
blocking high-energy waves from the Sun. Pick three high-energy waves
that the device should be able to block?
Answer:
1. Ultraviolet light (UV)
2. X-rays
3. Gamma-rays
Explanation:
Though there are different types of energy or electromagnetic waves with varying wavelengths, including the likes of Gamma X-rays, ultraviolet light, visible light, infrared radiation, and microwave radiation.
What is more certain is that the atmosphere blocked the high-energy waves from getting to the earth surface or biosphere such as Ultraviolet light (UV), X-rays and Gamma-rays

Okay actual answer, A heat engine is a mechanical energy converter that transforms heat or thermal energy to mechanical energy.
how to calculate acceleration
Answer:
Acceleration (a) is the change in velocity (Δv) over the change in time (Δt), represented by the equation a = Δv/Δt. This allows you to measure how fast velocity changes in meters per second squared (m/s^2). Acceleration is also a vector quantity, so it includes both magnitude and direction.
Explanation:
hope it help mark me as brill please
Answer:
acceleration equals the change in velocity divided by time

What is inertia and how can you increase an object's inertia?
Answer:
Explanation:
Inertia is the property of a body by virtue of which it opposes any agency that attempts to put it in motion or, if it is moving, to change the magnitude or direction of its velocity.
The more mass, the more inertia. If you increase the mass of the object then you increase the inertia.

If e is the electric field near an infinite sheet of charge and E is electric field between two similarly charged parallel plates then what will be the relation
Answer:
* the two plates of the same sign E = 0
* the two plates of different sign E/e = 2
Explanation:
In this exercise, the relationship between the field created by a plate and two infinite plates is asked.
The electric field created by each plate has the value of "e", which is related to the charge on the electric plate.
e = [tex]\frac{ \sigma }{2 \epsilon_o}[/tex]
If the plate is negative the electric field is directed towards the plate and if the plate is positive the electric field is directed out of the plate.
The test charge is always positive.
When we have two plates, we have several possibilities
* the two plates of the same sign
therefore the resulting electric field on the test charge is
E_total = e - e
E = 0
* the two plates of different sign
E_total = e + e
E = 2 e
the relationship between the two fields is
E/e = 2

Suppose that we replace the aluminum with a mystery metal and repeat the experiment in the video. As in the video, the mass of the metal is the same as that of the water. Room temperature is about 20∘C before the start of the experiment. The water heats up to 40∘C, and the mystery metal heats up to 80∘C. Compared to that of water, the heat capacity of our mystery metal is
Answer: b) one-third as great.
Explanation:
The options include:
a) three times greater.
b) one-third as great.
c) half as great.
d) two times greater.
e) the same.
Since the water heats up to 40°C and the room temperature is about 20°C before the start of the experiment, heat absorbed will be: (40°C-20°C).= 20°C
Since mystery metal heats up to 80∘C and the room temperature is about 20°C before the start of the experiment, heat absorbed will be: (80°C-20°C).= 60°C.
Therefore, based on the calculation, when compared to that of water, the heat capacity of our mystery metal is (20/60) = 1/3 one-third as great.
What will be the change of velocity of a 50kg object if a force of 2,000N
is applied to it for 0.010 seconds?
Answer:
0.4m/s
Explanation:
[tex]F = ma[/tex] where F= force, m= mass, and a=acceleration
we also know that,
a = Δv / t where Δv = change in velocity and t = time
thus F = m ( Δv / t)
[tex]2000=50(\frac{v}{0.01})[/tex]
[tex]\frac{2000}{5000} = v[/tex]
0.4m/s = Δv

_______ is the process which causes magma to form.
Answer:
flux melting
Explanation:
Flux melting is the process that causes magma to form. Flux melting happens when water or carbon dioxide exists added to rock.
What is meant by Flux melting?When rock is exposed to water or carbon dioxide, flux melting occurs. The rock melts at lower temperatures as a result of these substances. This causes magma to form where it had a solid structure before. Around subduction zones, flux melting also happens, much like heat transfer.
Flux melting happens in igneous petrology and volcanology when water and other volatile substances are added to hot solid rock, depressing the solidus. Flux is a material, such as salt, that produces a mixture with a metal oxide that has a low melting point (liquidus) in engineering and metallurgy.

The velocity of a car increases from +4.0 m/s to +16.0 m/s
in a time period of 4.0 s. What was the average
acceleration?
Answer:
Explanation:
Although we do have an equation for this in terms of one-dimensional motion, it's easy enough just to use the mathematical definition of acceleration:
[tex]a=\frac{v_f-v_0}{t}[/tex] which says, in words, the acceleration of an object is equal to the objects final velocity minus its initial velocity, divided by the change in time. Since everything is given in m and s, our answer will be in m/s/s:
[tex]a=\frac{16.0-4.0}{4.0}[/tex] and
[tex]a=\frac{12.0}{4.0}[/tex] so
a = 3.0 m/s/s

Explanation:
The thermal transfer of energy occurs in a solid like a copper rod following two process therefore the second process and method are
Lattice vibration and conduction
Lattice vibration is the movement/oscillation of atoms in a solid and this is caused by the change/increase in temperature applied to the solid and these vibrations will lead to the thermal transfer of energy via conduction since the atoms are bounded together .

If the specific heat of iron = 0.46J C, how much heat is needed to warm 50 g of iron from 20C to 100C
Answer:
1840 J
Explanation:
From the question given above, the following data were obtained:
Specific heat capacity (C) = 0.46 J/gºC
Mass (M) = 50 g
Initial temperature (T₁) = 20 °C
Final temperature (T₂) = 100 °C
Heat (Q) required =?
Next, we shall determine the change in the temperature. This can be obtained as follow:
Initial temperature (T₁) = 20 °C
Final temperature (T₂) = 100 °C
Change in temperature (ΔT) =?
ΔT = T₂ – T₁
ΔT = 100 – 20
ΔT = 80 °C
Finally, we shall determine the heat required. This can be obtained as follow:
Specific heat capacity (C) = 0.46 J/gºC
Mass (M) = 50 g
Change in temperature (ΔT) = 80 °C
Heat (Q) required =?
Q = MCΔT
Q = 50 × 0.46 × 80
Q = 1840 J
Thus, 1840 J of heat energy is required.
