A 2.0 kg block is pulled across a horizontal surface by a 15 N force at a constant velocity.a. What is the net force acting on the block?
Answer:
0
Explanation:
the block is being pulled at a constant velocity meaning it has no acceleration. the rule is fnet=mass x acceleration so if theres no acceleration there is no force net!
A block of mass 2 kg is pulled across a surface with a force of 15 N then the net force acting on the block is 0.
What is Force?A force is an effect that can alter an object's motion according to physics. A force might cause an object has mass to accelerate when it changes its velocity, for, us when it moves away from rest. An obvious way to describe force is in terms of push or pull. A force is a vector quantity since it has equal magnitude and direction. It is calculated using the newton SI unit (N). Force is denoted by the letter F.
The net force exerted by an object was equal to the speed at which its velocity varies over time, according to Newton's second law in its original formulation.
The block has no acceleration because it is being pushed at a constant speed. If there is no acceleration, there is no force net because the formula is net force =mass × acceleration.

A spring of natural length 10cm and spring constant 4.00Ncm −1 has a load of 22.0N placed on it. What is its new length?
Explanation:
Hooke's Law: Fe = kx
x = Fe / k = (22.0N) / (4.00N/cm) = 5.50cm.
10.00cm + 5.50cm = 15.50cm

Which graph accurately shows the relationship between kinetic energy and speed as speed increases?
Answer:
B
Explanation:
kinetic energy (KE) is the energy possessed by moving bodies. It can be expressed as:
KE = [tex]\frac{1}{2}[/tex]m[tex]v^{2}[/tex]
Where: m is the mass of the object, and v its speed.
For example, a stone of mass 2kg was thrown and moves with a speed of 3 m/s. Determine the kinetic energy of the stone.
Thus,
KE = [tex]\frac{1}{2}[/tex] x 2 x [tex]3^{2}[/tex]
= 9
KE = 9.0 Joules
Assume that the speed of the stone was 4 m/s, then its KE would be:
KE = [tex]\frac{1}{2}[/tex] x 2 x [tex]4^{2}[/tex]
= 16
KE = 16.0 Joules
Therefore, it can be observed that as speed increases, the kinetic energy increases. Thus option B is appropriate.

A distance of 0.002 m separates two objects of equal mass. If the gravitational force between them is
0.0104 N, find the mass of each object.
Answer: 24.97 kg
Explanation:
The gravitational force between two objects of masses M1, and M2 respectively, and separated by a distance R, is:
F = G*(M1*M2)/R^2
Where G is the gravitational constant:
G = 6.67*10^-11 m^3/(kg*s^2)
In this case, we know that
R = 0.002m
F = 0.0104 N
and that M1 = M2 = M
And we want to find the value of M, then we can replace those values in the equation to get
0.0104 N = (6.67*10^-11 m^3/(kg*s^2))*(M*M)/(0.002m)^2
(0.0104 N)*(0.002m)^2/(6.67*10^-11 m^3/(kg*s^2)) = M^2
623.69 kg^2 = M^2
√(623.69 kg^2) = M = 24.97 kg
This means that the mass of each object is 24.97 kg

All of the following processes are the ones that lead directly to the formation of sedimentary rock EXCEPT-
deposition of rock fragments.
O
freezing of water in cracks in rock.
o
melting of rock deep underground.
movement of wind that carries earth material.
Answer:
melting of rock deep underground.
Explanation:
The melting of rocks deep underground does not produce sedimentary rocks. Most igneous rocks are produced by this process.
When molten rocks underground called magma is solidified in the subsurface, it results into the formation of igneous bodies.
Sedimentary rocks forms by the accumulation of sediments. Inside the basin where the sediments are deposited, they are compacted, cemented and lithified. Chemical and physical weathering of rocks produces sediments.Which diagram shows a situation that would not produce an electric current in the wire?

What is Electrical energy?When put in an electromagnetic field, charged matter experiences a force due to the fundamental property of electric charge. Positive or negative electrical ions are possible.
When two charge are in opposition to one another, they repel one another. The term "neutral" refers to an object has no net charge. The early understanding of the way charged particles interact is now referred to as classical electrodynamics, and it is still true for issues that do not demand for taking into account quant phenomena.
Electrical charge is a preserved attribute, meaning that the net charged of an isolated system—that is, the sum of the positive and negative charges—cannot change. Particles at the subatomic level carry an electric charge.
The second diagram from the option will have no current in it because the wires are not connected with the battery, so the flow of current will not take place.

12. What is the photoelectric effect, and what experimental evidence led scientists
to discover it? Does this support the wave or particle theory of light? Why?
Answer:
Photoelectric effect, phenomenon in which electrically charged particles are released from or within a material when it absorbs electromagnetic radiation.
Explanation:
The effect is often defined as the ejection of electrons from a metal plate when light falls on it. In a broader definition, the radiant energy may be infrared, visible, or ultraviolet light, X-rays, or gamma rays; the material may be a solid, liquid, or gas; and the released particles may be ions (electrically charged atoms or molecules) as well as electrons. The phenomenon was fundamentally significant in the development of modern physics because of the puzzling questions it raised about the nature of light—particle versus wavelike behaviour—that were finally resolved by Albert Einstein in 1905. The effect remains important for research in areas from materials science to astrophysics, as well as forming the basis for a variety of useful devices.
The emission of electrons from the surface of a metal by the action of light is called photoelectric effect. This phenomenon indicates the behavior of light as particles called photons.
What is photoelectric effect ?The phenomenon of ejection of electrons from the surface of a metal when light of a suitable frequency falls on it is called photoelectric effect. Upon striking the surface of metals , light can set up an electric current which current which corresponds to the flow of electrons. This phenomenon is discovered by Einstein
For instance, visible light can cause ejection of electrons from the surface of metal like cesium which has low ionization enthalpy. This phenomenon is related to the observation that if light is considered as particles.
The particles of light is then called as photoelectrons or photons. Photoelectric effect find application in photoelectric cells used in colorimetry, spectrophotometers etc.
