Q2 ) Starting from rest on a level road a girl can reach a speed of 5m/s in 10 s on her bicycle, find
A) the acceleration
Answers
Answer:
0.5m/s²
Explanation:
Given parameters:
Initial velocity = 0m/s
Final velocity = 5m/s
Time taken = 10s
Unknown:
Acceleration of the bicycle = ?
Solution:
Acceleration is the rate of change of velocity with time.
Acceleration = [tex]\frac{v - u}{t}[/tex]
v is the final velocity
u is the initial velocity
t is the time taken
Insert the parameters and solve;
Acceleration = [tex]\frac{5-0}{10}[/tex] = 0.5m/s²
Lorries sometimes have a curved metal sheet fitted on top of the cab. Explain why as fully as you can ?.
Answers
Explanation:
A vehicle frame, also known as its chassis, is the main supporting structure of a motor vehicle to which all other components are attached, comparable to the skeleton of an organism.
Until the 1930s, virtually every car had a structural frame separate from its body. This construction design is known as body-on-frame. Over time, nearly all passenger cars have migrated to unibody construction, meaning their chassis and bodywork have been integrated into one another.
Nearly all trucks, buses, and most pickups continue to use a separate frame as their chassis
A block of cheese Bhangs from the ceiling by rope 1 A wheel of cheese Whangs from the block of
cheese by rope 2
What is the correct free body diagram for the block of cheese B?
URGENT
Answers
Answer:
Explanation:
KHAN ACADEMY
The correct free body diagram is option (B). There will only be two forces acting on cheese B.
Given that Cheese B hangs on rope 1. The weight of the cheese is balanced by the tension force on the rope. That is, the cheese experiences a force in the upward direction due to the tension on rope 1.Similarly, a wheel of cheese W hangs from block B by a rope 2. This rope has a tensional force that is balanced by the weight of the cheese W. This causes a downward pull on block B due to the tension on rope 2.By representing the tensional forces by the ropes 1 and 2 as [tex]F_{T1}[/tex] and [tex]F_{T2}[/tex] respectively, the correct free body diagram will be option B.

A student tries to measure the period of a pendulum that is already swinging
left and right. At the moment when the pendulum is fully to the left, she
counts 'One' and starts a stopwatch. She counts successive swings each time
that the pendulum returns to the left. When she counts ‘Ten' she stops the
stopwatch, and sees that it reads 12.0 s.
a. What was her mistake?
______________________________________________________________
b. What is the period of swing of this pendulum?
______________________________________________________________
c. In this particular experiment, explain the likely effect of her reaction time
on her answer.
Answers
Answer:
a. The student's mistake was that the student did not swing the pendulum and start the watch at the same time.
b. 1.2 s per swing.
c. The likely effect of her reaction time is that they will should subtract two seconds off the time.
Explanation:
The pupil made the error of not simultaneously starting the watch and swinging the pendulum.
What is pendulum?Pendulum is defined as a body that is suspended from a fixed point and moves back and forth while being pulled by gravity. The pendulum is used to gauge the gravitational pull because the force of gravity causes it to swing back toward its average position. A pendulum's time period can be used to tell the time because it is constant.
The swing of the pendulum is 1.2 sec. per swing. They should take two seconds off the timing due to her presumably slow reaction time. A pendulum's total time should be divided by the quantity of oscillations in order to determine its time period. When compared to a pendulum with a shorter string, the one back and forth cycle of a longer-stringed pendulum requires more time to complete.
Thus, the pupil made the error of not simultaneously starting the watch and swinging the pendulum.

A dryer runs on 240 V with a resistance of 30.0 Ω. What is the current of the dryer?
Answers
Answer:
Current, I = 8 Amps
Explanation:
Ohm's law states that at constant temperature, the current flowing in an electrical circuit is directly proportional to the voltage applied across the two points and inversely proportional to the resistance in the electrical circuit.
Mathematically, Ohm's law is given by the formula;
[tex] V = IR[/tex]
Where;
V represents voltage measured in voltage.
I represents current measured in amperes.
R represents resistance measured in ohms.
Given the following data;
Resistance, R = 30 ohms
Voltage, V = 240V
To find the current;
[tex] I = \frac {V}{R} [/tex]
[tex] I = \frac {240}{30} [/tex]
Current, I = 8 Amps
Therefore, the current of the dryer is 8 Amperes.

A large truck of mass 5000 kg is travelling at 5.0 m/s.
A motorbike has a mass of 200 kg. Both the truck and the motor bike have the same kinetic energy
What is the speed of the motorbike?
A 25 m/s
B 10 m/s
C 125m/s
D 2.5 m/s
Answers
Answer:
A - 25m/s
Explanation:
The velocity of the motorbike will be 25 m/s in order to ensure that the truck and the motor bike have the same kinetic energy.
What is Kinetic Energy?The kinetic energy of the body is by the virtue of its motion.
Given is a large truck of mass 5000 kg which is travelling at 5.0 m/s and a motorbike that has a mass of 200 kg. Both the truck and the motor bike have the same kinetic energy.
The Kinetic energy of the truck will be -
E[T] = 1/2 mv² = 1/2 x 5000 x 25 = 2500 x 25 = 62500 joules
Then Kinetic energy of the motorbike will be -
E[M] = 1/2 x 200 x v²
E[M] = 100v² joules
Now-
E[T] = E[M]
100v² = 62500
v² = 625
v = 25 m/s
Therefore, the velocity of the motorbike will be 25 m/s in order to ensure that the truck and the motor bike have the same kinetic energy.
