To compare the magnitude of the inertia of the bowling and tennis ball, we take the ratio of their masses. Hence, the bowling ball has 100 times the inertia of the tennis ball.
Given the Parameters :
Mass of bowling ball = 6 kilogram Mass of tennis ball = 0 06 kilogramTaking the ratio of the masses :
Mass of bowling ball / Mass of tennis ballInertia = 6kg / 0.06kg
Inertia = 100
Hence, the inertia of the bowling ball is 100 times that of the tennis ball.

what is electricity
Electricity is the set of physical phenomena associated with the presence and motion of matter that has a property of electric charge. Electricity is related to magnetism, both being part of the phenomenon of electromagnetism, as described by Maxwell's equations.
a form of energy resulting from the existence of charged particles (such as electrons or protons), either statically as an accumulation of charge or dynamically as a current.

. A small toy car having 300 grams of mass and going straight with an initial velocity of 13 m/s. When the toy car collides with an obstacle, a resistive force of 4 N acts upon it. The speed of the toy car reduced and reached 8 m/s. Draw its free body diagram and then find the time for the toy car to be into rest position?
The free-body diagram is attached in the image below. The time for the toy car to be in rest position is 0.6 s
From the given information:
The mass of the toy car = 300 g = 0.3 kgThe initial velocity (u) of the car = 13 m/sThe resistive force F_r acting on the car = 4 NThe speed of the car (v) = 8 m/sA force is regarded as a push that causes an alteration in motion of an object within a specified distance. It is usually expressed by the formula:
Force = mass × acceleration∴
acceleration = Force/massacceleration = (4 / 0.3) m/s²acceleration = 13.33 m/s²Using the first equation of motion for the time to bring the car to rest from it reduced speed of 8 m/s;
v' = v + atsince the final speed to bring the car in rest position is (0), then:
0 = 8 - 13.33(t)
13.33(t) = 8
t = 8/13.33
t = 0.6 seconds

calculate the mass fo an unknown solid if its density is 1.6 g/cm^3 and it has a length of 7.5 cm, a height of 12.5 cm, and a width of 2.2 cm
Answer:
Density = Mass / Volume
Mass = Density * volume = 1.6 gm/cm^3 * (7.5 * 12.5 * 2.2) cm^3
Mass = 1.6 gm/cm^3 * (206 cm^3) = 330 gm

A bird flies at a speed of 9.0 m/s in still air. If the bird flies with a 12 m/s
crosswind blowing, how fast does it travel relative to the ground?
If a bird flies at a speed of 9.0 meters / second in still air. If the bird flies with 12 meters / second crosswind blowing, the bird's speed relative to the ground would be 15 meters/second.
What is a vector quantity?The quantities that contain the magnitude of the quantities along with the direction are known as the vector quantities.
As given in the problem If a bird flies at a speed of 9.0 meters / second in still air. If the bird flies with 12 meters / second crosswind blowing,
The speed of the bird relative to the ground = √(9² + 12²)
=√225
=15 meters / second
Thus, the speed of the bird relative to the ground would be 15 meters/second.

A.5.6
B.3.1
C.3.73
D.4.4J
Answer:
D: 4.4m/s
Explanation:
From a known theorem the total work on a body is equal of the variation of kinetic energy:
[tex]W = \Delta K = K_f-K_i = \frac12 mv_f^2 - \frac12 m v_i^2[/tex]
Taking the first and last step in the chain of equalities and replacing the values we have, we get:
[tex]5 = \frac12(1)v_f^2 - \frac12(1)(3)^2\\10= v_f^2 -9 \rightarrow v_f^2 = 19 \rightarrow v_f=\sqrt19 \approx 4.4m/s[/tex]

an amusement park ride has two identical carriages that revolve around the center of the ride’s axle, as shown in the figure. both carts travel at a constant tangential speed at all points along the circular path. at what position is the total mechanical energy of the cart-cart-earth system at its maximum value?
The principle of conservation of energy allows to find the result for the mechanical energy of the system is:
Mechanical energy is conserved at all points, therefore at all points it has the same value.
Mechanical energy is defined by the sum of the kinetic energy and the potential energies.
Em = K + U
In the principle of energy conservation, it establishes that energy cannot be created or destroyed, it is only transformed, in the case of no friction, mechanized energy is conserved at all points.
They indicate that the system is rotating, which is why it is subjected to a force that expends its energy in changing the direction of the speed to keep the system in rotation, so the speed of the system remains constant.
Em = K = ½ I w²
Consequently, using the principle of conservation of energy we can find the result for the mechanical energy of the system is:
Mechanical energy is conserved at all points, therefore at all points it has the same value.

A skydiver jumps from an airplane that is moving at 50 meters per second at a height of 1,000 meters what describes the skydivers energy immediately after leaving the air plane
Answer:
11060M Joules, where M is the mass of the diver in kg
Explanation:
Mass of the skydiver missing, we're assuming it's M.
It's total energy is the sum of the contribution of his kinetic energy (K)- since he's moving at 50 m/s, and it's potential energy (U), since he's subject to earth gravity.
Energy is the sum of the two, so [tex]E = K+U= \frac 12 M v^2 + Mgh = M (\frac 12 \cdot 50^2 + 9.81\cdot 1000) = M ( 1250 + 9810) = 11060\cdot M[/tex]
Find a unit vector perpendicular to the vectors given A=4i+2j+2k and B=4i-4j+8k.
The cross product of A and B is perpendicular to both A and B.
A × B = (4i + 2j + 2k) × (4i - 4j + 8k)
A × B = 16 (i × i) - 16 (i × j) + 32 (i × k) + 8 (j × i) - 8 (j × j) + 16 (j × k) + 8 (k × i) - 8 (k × j) + 16 (k × k)
A × B = -16 (i × j) - 32 (k × i) - 8 (i × j) + 16 (j × k) + 8 (k × i) + 8 (j × k)
A × B = -16k - 32j - 8k + 16i + 8j + 8i
A × B = 24i - 24j - 24k
The magnitude of A × B is
||A × B|| = 24 ||i - j - k|| = 24√3
Dividing A × B by its magnitude gives a unit vector,
(A × B)/||A × B|| = 1/√3 (i - j - k)
