VERY IMPORTANT PLS ANSWER!!!!!!!
The weight of an object can be determined by multiplying the mass of the object by which of the following?
A the object's velocity
B the object's size
C the object's change in speed
D the object's acceleration due to gravity
Answer:
A, the objects velocity
Explanation:
as an object falls:
a) both velocity and acceleration increase
b) velocity increases and acceleration decreases
c) velocity increases and acceleration is unchanged
Answer:
c it is not accelerating on it's on but gravity pulls it there for velocity increases.
As an object falls, velocity increases and acceleration is unchanged. Therefore, option C is correct.
What do you mean by velocity ?The term velocity is defined as the direction of the movement of the body or the object.
Speed is fundamentally a scalar quantity. Velocity is, in essence, a vector quantity. It is the rate at which distance changes. It is the displacement rate of change.
The velocity of something is the rate at which it moves in a specific direction. For example, the speed of a car driving north on a highway or the speed of a rocket after launch. The scalar denotes that the absolute magnitude of the velocity vector is always the speed of motion.
Thus, it is not accelerating on it's on, but gravity pulls it there as velocity increases.

A massive tractor is rolling down a country road. In a perfectly inelastic collision, a small sports car runs into the machine from behind. (i) Which vehicle experience a change in momentum of larger magnitude? (a) The car does. (b) The tractor does. (c) Their momentum changes are the same size. (d) It could be either vehicle. (ii) Which vehicle experiences a larger change in kinetic energy? (a) The car does. (b) The tractor does. (c) Their kinetic energy changes are the same size. (d) It could be either vehicle.
Explanation:
In an inelastic collision, the momentum remains conserved while the kinetic energy is not conserved.
(i) Here, a small sports car runs into the machine from behind.
Due to the conservation of momentum, it remains conserved. It means their momentum changes are the same size.
Hence, the correct option is (c).
(ii) The car is moving faster than the tractor. A faster moving object will lose more energy as compared to the other. It means car's most of the energy is converted to internal energy. The car will have a a larger change in kinetic energy. Hence, the correct option is (a).

Why is a cell phone more likely to break when dropped from a higher height than a lower one?
A cell phone more likely to break when dropped from a higher height than a lower one because it has more potential energy at high height.
What is potential energy?Potential energy is the energy stored by an object as a result of its position relative to other objects, internal tensions, electric charge, or other reasons.
Potential energy is commonly defined as an object's gravitational potential energy, the elastic potential energy of an extended spring, and the electric potential energy of an electric charge in an electric field. The joule is the SI unit of energy.
Although it has connections to the Greek philosopher Aristotle's concept of potentiality, the word potential energy was coined by the 19th-century Scottish engineer and physicist William Rankine.

On 16th August 2020, an asteroid (later called 2020 QG) has been recorded as the closest
asteroid (spotted so far) that flew by the Earth without colliding with it. At the nearest point
of approach, it was only 2 950 km above Earth’s surface and it had a velocity v = 12.3 km·s
−1
.
How much higher was its velocity compared to the escape velocity at that height above Earth’s
surface? Find the ratio v/vesc.
Answer:
V/Ve = 1.1
Explanation:
The formula to find the escape velocity of an object at a distance from Earth's Surface is given as follows:
Ve = √[2GM/R]
where,
Ve = escape velocity = ?
G = Universal Gravitational Constant = 6.67 x 10⁻¹¹ N.m²/kg²
M = Mass of Earth = 5.97 x 10²⁴ kg
R = Radius of Earth = 6.37 x 10⁶ m
Therefore,
Ve = √[2(6.67 x 10⁻¹¹ N.m²/kg²)(5.97 x 10²⁴ kg)/(6.37 x 10⁶ m)]
Ve = 11.2 x 10³ m/s = 11.2 km/s
Hence, the ratio will be:
V/Ve = (12.3 km/s)/(11.2 km/s)
V/Ve = 1.1

A 2.93 kg particle has a velocity of (2.98 i hat - 3.98 j) m/s.
Required:
a. Find its x and y components of momentum.
b. Find the magnitude and direction of its momentum.
Answer:
a) The x and y components of the momentum are [tex]8.731\,\frac{kg\cdot m}{s}[/tex] and [tex]-11.661\,\frac{kg\cdot m}{s}[/tex], respectively.
b) The magnitude and direction of its momentum are approximately 14.567 kilogram-meters per second and 306.823º.
Explanation:
a) The vectorial equation of momentum is represented by the following expression:
[tex]\vec p = m\cdot \vec v[/tex] (1)
Where:
[tex]\vec p[/tex] - Vector momentum, measured in kilogram-meters per second.
[tex]m[/tex] - Mass of the particle, measured in kilograms.
[tex]\vec v[/tex] - Vector velocity, measured in meters per second.
If we know that [tex]m = 2.93\,kg[/tex] and [tex]\vec v = 2.98\,\hat{i}-3.98\,\hat{j}\,\,\,\left[\frac{m}{s} \right][/tex], then the momentum is:
[tex]\vec p = (2.93)\cdot (2.98\,\hat{i}-3.98\,\hat{j})\,\,\,\left[\frac{kg\cdot m}{s} \right][/tex]
[tex]\vec p = 8.731\,\hat{i}-11.661\,\hat{j}\,\,\,\left[\frac{kg\cdot m}{s} \right][/tex]
The x and y components of the momentum are [tex]8.731\,\frac{kg\cdot m}{s}[/tex] and [tex]-11.661\,\frac{kg\cdot m}{s}[/tex], respectively.
b) The magnitude and direction of momentum are represented by the following expressions:
[tex]\|\vec p \| = \sqrt{p_{x}^{2}+p_{y}^{2}}[/tex] (2)
[tex]\theta = \tan^{-1}\left(\frac{p_{y}}{p_{x}} \right)[/tex] (3)
Where:
[tex]\|\vec p\|[/tex] - Magnitude of momentum, measured in kilogram-meters per second.
[tex]\theta[/tex] - Direction of momentum, measured in sexagesimal degrees.
If we know that [tex]p_{x} = 8.731\,\frac{kg\cdot m}{s}[/tex] and [tex]p_{y} = -11.661\,\frac{kg\cdot m}{s}[/tex], then the magnitude and direction of momentum are, respectively:
[tex]\|\vec p\| = \sqrt{\left(8.731\,\frac{kg\cdot m}{s} \right)^{2}+\left(-11.661\,\frac{kg\cdot m}{s} \right)^{2}}[/tex]
[tex]\|\vec p\| \approx 14.567\,\frac{kg\cdot m}{s}[/tex]
[tex]\theta =\tan^{-1}\left(\frac{-11.661\,\frac{kg\cdot m}{s} }{8.731\,\frac{kg\cdot m}{s} } \right)[/tex]
[tex]\theta \approx 306.823^{\circ}[/tex]
The magnitude and direction of its momentum are approximately 14.567 kilogram-meters per second and 306.823º.
Which elastic modulus describes the relationship between stress and strain for a block of iron sliding across a horizontal floor? The friction force between the sliding block and the floor causes the block to deform.
A. Young's Modulus
B. Shear Modulus
C. Bulk Modulus
D. None of these
Answer:
B. Shear Modulus
Explanation:
In this scenario, the friction force between the sliding block and the floor causes the block to deform.
Hence, the elastic modulus which describes the relationship between stress and strain for a block of iron sliding across a horizontal floor is Shear Modulus.
Shear Modulus can be defined as the ratio of shear stress to shear strain with respect to a physical object.
This ultimately implies that, Shear Modulus arises as a result of the application of a shear force on an object or body which eventually leads to its deformation. Thus, this phenomenon is simply used by scientists to measure or determine the rigidity of an object or body.
Mathematically, Shear Modulus is given by the formula;
[tex] G = \frac {Fl}{ADx} [/tex]
Where;
G is the Shear Modulus.
F is the force applied to the object.
A is the area of the object.
l is the length of the object.
Dx is the change in length.
Shear Modulus is measured in Pascals.
