A car accelerates at a rate of 8.8m/s² with a force from the tires of 19,976N. What is the mass of the car?
A.1800kg
B.2270kg
C.1360kg
D2140kg
Answers
Answer:
B. 2270 kg
Explanation:
We know that :
Force = Mass x AccelerationWe are given :
Force = 19,976 NAcceleration = 8.8 m/s²Finding mass
19,976 = 8.8 x massmass = 19,976/8.8mass = 2270 kgA book weighing 1.2 kg stands on the table. We place our hand on the book with a force of 15.3 N. The reaction force of the table base to the book is: a) 12 N b) 15 N c) 22 N d) 27 N e) 33 N
Answers
Answer:
27 N
Explanation:
It will be the force of the book 1.2 kg * 9.81 m/s^2 PLUS the force of your hand 15.3 N ..... it will be in the OPPOSITE direction
1.2 * 9.81 + 15.3 = ~27.1 N

A 3.0kg weight W is initially at rest on incline AB, which is raised 40° above the horizontal. The effective coefficient is
mu = 0.3 . Through frictionless pulley and strings of negligible mass, a small mass P, 400g, is at rest on a 200g weighting pan.
Draw a free body diagram representing the situation, and use it to determine the acceleration of the system. Use the value of acceleration calculated to determine the relative weight of P in pounds.
Answers
(a) The acceleration of the system is determined as 1.58 m/s².
(b) The relative weight of P is pounds is determined as 0.14 lb.
Acceleration of the system
The acceleration of the system is calculated as follows;
W - T = m₂a --- (1)
T = m₁a ----(2)
μmgsinθ - m₁a = m₂a
(0.3 x 3 x 9.8 x sin40) - (0.4 + 0.2)a = 3a
5.67 - 0.6a = 3a
5.67 = 3.6a
a = 5.67/3.6
a = 1.58 m/s²
Relative Weight of PW = ma
W = 0.4 x 1.58

If a constant force of 917 N is exerted on a scooter for 6 s, thenwhat is the change in momentum?
a 6 kg-m/s
b 5502 kg-m/s
c 917 kg-m/s
d 153 kg-m/s
Answers
Answer: 917
Explanation:
The change in momentum if a constant force of 917 N is exerted on a scooter for 6s is 5502kg-m/s.
How to calculate momentum?Momentum is the tendency of a body to maintain its inertial motion. It is the product of its mass and velocity, or the vector sum of the products of its masses and velocities.
Force = mass x (velocity/time)
Force = (mass x velocity)/time
Force = momentum/time
According to this question, a constant force of 917 N is exerted on a scooter for 6s. The change in momentum is calculated as follows:
917N = p/6
p = 5502kg-m/s
Therefore, 5502kg-m/s is the change in momentum of the scooter.

Find the direction of their

Answers
The magnitude of the vector sum of the two vectors V and W is determined as 240.84 m toward + x.
What is a vector?A vector is a quantity or phenomena with magnitude and direction that are independent of one another. The phrase also refers to a quantity's mathematical or geometrical representation.
The following are the x and y axes for the supplied vector:
Vector V in x direction;
[tex]\rm V_x = Vcos \theta \\\\ V_x = 448cos(224^0)\\\\ Vx = -322.26[/tex]
Vector V in y direction;
[tex]\rm V_y = Vsin \theta\\\\ V_y = 448 \times sin224^0\\\\ V_y = -311.2[/tex]
Vector W in x direction;
[tex]\rm W_x = 336 \times cos(75.9^0)\\\\ W_x = 81.86[/tex]
Vector W in y direction;
[tex]\rm W_y = 336 \times sin75.9\\\\\ W_y = 325.88[/tex]
The resultant vector in the x direction is;
∑X = -322.26 + 81.86
∑X == -240.4
The resultant vector in the y direction is;
∑Y = -311.2 + 325.88
∑Y = 14.68
The resultant vector is found as;
[tex]\rm R =\sqrt{(-240.4)^2+(14.68)^2} \\\\R = 240.84 \ m[/tex]
Hence, the direction of their vector sum is 240.84 toward +x-axis.

car accelerates from rest at 4.5 m/s² for 3 seconds.
a. What is the car's velocity after 3 seconds?
b. What distance does the car travel in the 3 seconds?
m/s
Answers
A car accelerates from rest at 4.5 m/s² for 3 seconds, the car's velocity after 3 seconds is 13. 5 m/s
The distance the car travel in the 3 seconds is 40. 5m/s
The first equation of motion is v = u + a t. It explains the relationship between velocity and time.
V = Final velocity
u = Initial velocity
a = acceleration
t = time.
How to determine the velocity
When an object is brought to rest or moves from resting, U, initially velocity equals 0.
From the formula,
V = u + at
V = ?
u = 0, because the object was at rest.
a = 4. 5 m/ s²
t = 3 seconds
Velocity, V = 0 + 4. 5 × 3
Velocity , V = 0 + 13. 5
Velocity, V = 13.5 m/s²
How to determine the distance
Velocity = Distance ÷ time
Velocity, V = 13. 5 m/s²
time = 3 seconds
distance = ?
Distance = Velocity × time
Distance = 13. 5 × 3
Distance = 40. 5 m
Therefore, the car's velocity after 3 seconds is 13. 5 m/s² and the distance the car travels after 3 seconds is 40. 5m

C. The United Kingdom
D. Japan
Answers
Japan is the answer
In the text "White House Press Release Announcing the Bombing of Hiroshima August 6, 1945" by President Truman, the atomic bomb was developed by the United States. Therefore, the correct answer is B. The United States.
During World War II, a top-secret project known as the Manhattan Project was conducted by the United States. The goal of this project was to develop an atomic bomb. The research and development efforts were led by American scientists, engineers, and military personnel. The project involved numerous facilities across the United States, including Los Alamos, New Mexico, where the final design and testing of the atomic bomb took place.
President Truman's press release announcing the bombing of Hiroshima on August 6, 1945, indicates that the United States successfully developed and deployed the atomic bomb. This historical event marked the first use of atomic weapons in warfare and had a significant impact on the outcome of World War II.
Therefore, based on the context of President Truman's press release and the historical record, it is clear that the atomic bomb was developed by the United States. Therefore, the correct answer is B.

Q32.4 Sometimes neon signs located near a powerful radio station are seen to glow faintly at night, even though they are not turned on. What is happening?
Answers
Neon lamps located near a powerful radio station are seen to glow faintly at night because radio waves may generate a potential difference in the neon gas.
What is a neon lamp?A neon lamp is a lamp containing neon gas as well as other types of gases and two electrodes.
In a neon lamp, the electricity is generated by striping negative electrons from neon atoms, which ionize these atoms.
The radio waves can also ionize atoms in the neon lamp by generating a potential difference in the neon particles of the lamp, thereby glowing faintly at night.
In conclusion, neon signs located near a powerful radio station are seen to glow faintly at night because radio waves may generate a potential difference in the neon gas.
