Which of the following actions will increase the inertia of a shopping cart?
-Adding items to the cart
-
-Removing the wheels from the cart
O Rearranging items in the cart
Oiling the cart's wheels
Answer:
A. Adding items to the cart
Explanation:
Inertia can be defined as the tendency of an object or a body to continue in its state of motion or remain at rest unless acted upon by an external force.
In physics, Sir Isaac Newton's first law of motion is known as law of inertia and it states that, an object or a physical body in motion will continue in its state of motion at continuous velocity (the same speed and direction) or, if at rest, will remain at rest unless acted upon by an external force.
The inertia of an object such as a shopping cart is greatly dependent or influenced by its mass; the higher quantity of matter in a shopping cart, the greater will be its tendency to continuously remain at rest.
Hence, adding items to the cart is an action which will increase the inertia of a shopping cart, by increasing its tendency to be at rest.
Adding items to the cart will increase the inertia of a shopping cart.
Inertia refers to the resistance that an object has to modify its velocity and/or direction during movement. Inertia not only includes the speed of the object but also the direction of its movement.Inertia also can be described as the inherent tendency of a given object to resist changes in its state of movement (motion).In conclusion, adding items to the cart will increase the inertia of a shopping cart.

As a pendulum swings from its highest to its lowest position along an arc, what happens to its kinetic energy and potential energy?
At its highest position along the arc, the pendulum is at its lowest point of kinetic energy but its highest point of potential energy. As it swings to the lowest position, the potential energy is converted into kinetic energy, thus decreasing potential energy and increasing kinetic energy.

A supersonic jet flying at 100 m/s is accelerated uniformly at the rate of 20 m/s2 for 20 s. What is its final velocity?
If it takes 100 N to move a box 5 meters, what is the work done on the box?
A. 20 J
B. 5,000 J
C. 5 J
D. 500 J
Answer: D. 500 J
=========================================================
Explanation:
To find the amount of work done, we multiply the force by displacement
work = force*displacement
work = (100 N)*(5 m)
work = (100*5) Nm
work = 500 J
In this case, "Nm" refers to "Newton meters" and not "nanometers"
1 newton meter is equal to 1 joule
How is a metre related to kilometre?
Answer:
The kilometer is unit of length in the metric system equivalent to one thousand meters. 1Km is equivalent to 0.6214 miles.
Explanation:
Length is the measurement of the distance from the initial point to the final point.
________________________________________________________
SI Unit:The Si unit of length is meter, that means length is measured in meter units.
____________________________________Relation:The Relation between meter and kilometer is that they both are the units of the length, also the Kilometer(Km) is equals to the 1000 meters(m).
1Km = 1000 meter
1m = 0.001 Km

A Boy has a ball and throws it straight up into the air with an initial velocity of 6 m/s. Calculate the maximum height of the ball and the time the ball is in the air.
Answer:
i. 1.84 m
ii. The ball's time in the air is 1.23s.
Explanation:
The ball moves upward (against the gravitational pull) with an initial velocity of 6 m/s.
I. Applying the third equation of free fall, the maximum height is;
[tex]V^{2}[/tex] = [tex]U^{2}[/tex] - 2gs
where the variables have there usual meaning.
[tex]V^{2}[/tex] = 0 m/s, [tex]U^{2}[/tex] = 6 m/s, g = 9.8 m/[tex]s^{2}[/tex].
0 = [tex]6^{2}[/tex] - 2 x 9.8 x s
0 = 36 - 19.6s
⇒ 19.6s = 36
s = [tex]\frac{36}{19.6}[/tex]
= 1.8367
= 1.84 m
The maximum height of the ball is 1.84 m.
II. The time the ball was in air can be determined by,
time of flight, T = [tex]\frac{2USin A}{g}[/tex]
where U is the initial velocity of the ball, A is the angle of projection and g is the acceleration due to gravity.
U = 6 m/s, A = [tex]90^{o}[/tex] (since the ball is thrown vertically upward), and g = 9.8 m/[tex]s^{2}[/tex].
T = [tex]\frac{2 *6 Sin90^{o} }{9.8}[/tex]
= [tex]\frac{12}{9.8}[/tex]
= 1.2245
T = 1.23s
The ball's time in the air is 1.23s.

[tex]From\ the\ information\ provided, \ we\ know\ that:\\Initial\ velocity\ of\ the\ car=25\ m/s\\Final\ velocity\ of\ the\ car=60\ m/s\\\\Acceleration=5\ m/s^2\\[/tex][tex]As\ we\ know\ that\ , \\Acceleration=\frac{Change\ in\ velocity}{Change\ in\ time} \\a=\frac{v-u}{t} \\Hence,\\t=\frac{v-u}{a} \\Substituting\ u=25,v=60,a=5,\\t=\frac{60-25}{5}\\t=\frac{35}{5}\\t=7\ seconds[/tex]

Marla made ice by freezing liquid water the freezerWhat did the freezer do to cause the change in the water?
Answer:
It slowed the kinetic energy of the water.
Explanation:
When you freeze something, the cold air slows down the kinetic energy of that object. There is no actual "cold" but there *is* a lack of heat, and this is proven in that example. Since temperature is a measure of how much kinetic energy an object has, the lack of kinetic energy would make the objects colder. Therefore, when you put a bottle of water into the freezer, by slowing the kinetic energy of the water, it freezes it!

a small asteroid of mass 125 kg is orbiting a planet that has a mass of 3.52x 10^13 what is the radial distance between the asteroid and the planet of the tangential velocity of the asteroid is 0.034m/s
Answer:
r = 2.031 x 10⁶ m = 2031 km
Explanation:
In order for the asteroid to orbit the planet, the centripetal force must be equal to the gravitational force between asteroid and planet:
Centripetal Force = Gravitational Force
mv²/r = GmM/r²
v² = GM/r
r = GM/v²
where,
r = radial distance = ?
G = Universal Gravitational Constant = 6.67 x 10⁻¹¹ N.m²/kg²
M = Mass of Planet = 3.52 x 10¹³ kg
v = tangential speed = 0.034 m/s
Therefore,
r = (6.67 x 10⁻¹¹ N.m²/kg²)(3.52 x 10¹³ kg)/(0.034 m/s)²
r = 2.031 x 10⁶ m = 2031 km

Un vagón de carga de 5000-kg se mueve a 2m/s e impacta a un vagón de 10000-kg que se encuentra en reposo. Después de la colisión inelástica a que rapidez se mueven.
Answer:
0.67 m/s
Explanation:
Mass of car 1, m₁ = 5000 kg
Mass of car 2, m₂ = 10,000 kg
Initial speed of car 1, u₁ = 2 m/s
Final speed of car 2, u₂ = 0 (at rest)
We need to find the final velocity of both cars when inelastic collision occurs. The momentum will remain conserved in case of inelastic collision. Using the conservation of momentum. Let V is the final speed.
[tex]m_1u_1+m_2u_2=(m_1+m_2)V\\\\\V=\dfrac{m_1u_1+m_2u_2}{(m_1+m_2)}\\\\V=\dfrac{m_1u_1}{(m_1+m_2)}\\\\V=\dfrac{5000\times 2}{(5000+10000)}\\\\V=0.67\ m/s[/tex]
So, after the inelastic collision, they will move with a speed of 0.67 m/s.

A projectile is fired with an initial speed of 37.0 m/s at an angle of 43.7 ∘ above the horizontal on a long flat firing range. What is the maximum height.
Answer:
The maximum height reached by the projectile is 33.34 m
Explanation:
Given;
initial velocity of the projectile, u = 37 m/s
angle of projection, θ = 43.7°
The maximum height reached by the projectile = ?
Apply the following kinematic equation, to determine the maximum height reached by the projectile.
Maximum height (H) is given as;
[tex]H = \frac{u^2 sin^2\theta}{2g}\\\\ H = \frac{(37)^2 (sin 43.7)^2}{2*9.8}\\\\H = 33.34 \ m[/tex]
Therefore, the maximum height reached by the projectile is 33.34 m
