Answer:
13800N
Explanation:
15000N is the force of motorbike
1200N is air resistance in opposite direction
15000N-1200N=13800N
Answer:
Ft = 13800 [N]
Explanation:
We have to carry out a force analysis and assume the directions of those forces. First the force that causes the movement of the rider is equal to 15000 [N] and is directed to the right. Since the resistance of the air is opposite to the movement, it generates a resistance with a value of 1200 [N], with direction to the left. However, the rider continues to move to the right, as the force generated by the bike is greater, i.e. this force must be to the right for movement to exist. By means of a summation of forces on the X axis we can calculate the value of the resulting force. The forces to the right will be taken with a positive sign and the forces to the left with a negative sign.
15000 - 1200 = Ft
where:
Ft = unbalanced force [N]
Ft = 13800 [N]

What are the variables do you think to be considered to determine the acceleration of an object?
What is the wavelength of a water wave that is moving at 12 m/s with a frequency of 3 Hz?
Answer:
it is 4m
Explanation:
state Newton's second law of
motion and write down
three examples to
justity it.
Answer:
The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object.
[tex]f = m \times a[/tex]
f= force
m=mass
a=acceleration
Explanation:
examples:
riding your bicycle
•your bicycle is the mass, your leg pushing in pedals of your bicycle is the force
pushing a box
•the box is the mass, you are pushing the box
setting a pencil down in a table
•the pencil is the mass, you are puting the pencil down
A boy stands at a certain distance from a large building and blows a whistle. After 2.3s he hears the echo of the sound. He moves 50m towards the building and blows his whistle again; this time the echo reaches him after 2.0s. Calculate thei. Boys original distance from the building ii. Speed of sound in air
Answer:
I) 57.5 m
Il) 50 m/s
Explanation:
Given that a boy stands at a certain distance from a large building and blows a whistle.
After 2.3s he hears the echo of the sound. The speed V of the sound will be:
V = 2X / T
Where X is the distance covered
V = 2X / 2.3
V = 0.87X ...... (1)
He moves 50m towards the building and blows his whistle again; this time the echo reaches him after 2.0s.
V = (2×50) / 2
V = 50 m/s
Substitutes the V into equation 1
50 = 0.87X
X = 50 / 0.87
57.5 m
Therefore, the Boys original distance from the building is 57.5m and the
Speed of sound in air is 50m/s

The primary source of power for the wheel and axle in a remote-controlled car would be:
- Chemical energy from the batteries.
Chemical Energy
The key source that offers power to the wheel, as well as, the axle in the remote-controlled car would be 'the chemical energy that is released from the batteries.'These chemical energies would allow the car to function on the commands given by the remote.

Which describes one event that causes an eclipse?
Pick One.
Earth’s rotation on its axis
shadows from clouds covering Earth
Earth’s shadow covering the moon
the gravity from the moon and Sun pulling in the same direction
Answer:
c. earth's shadow covering the moon
Explanation:
One thing that produces an eclipse is when Earth's shadow covers the moon and the moon and Sun's gravitational pull on each other. Option C is correct.
What is a solar eclipse?When the moon passes in front of Earth and the sun, it creates a solar eclipse and casts a shadow across the globe.
A solar eclipse can occur only during the new moon phase when the moon travels squarely between the sun and Earth and casts shadows on its surface.
Earth’s shadow covers the moon the gravity from the moon and Sun describes one event that causes an eclipse.

A toddler drops his pacifier from the Royal Gorge Bridge in Colorado. If the pacifier took 7.71 s to fall how fast was it traveling when it hit the water?
Answer:
75.56 m/s
Explanation:
The following data were obtained from the question:
Initial velocity (u) = 0 m/s
Time (t) = 7.71 s
Acceleration due to gravity (g) = 9.8 m/s²
Final velocity (v) =..?
Thus, we can obtain the velocity (v) with which the pacifier hit the water as follow:
v = u + gt
v = 0 + (9.8 × 7.71)
v = 0 + 75.558
v = 75.558 ≈ 75.56 m/s
Therefore, velocity with which the pacifier hit the water is 75.56 m/s

How can Newton's third law describe the forces affecting a rocket as it
descends to Earth's surface?
Answer:
His third law states that for every action (force) in nature there is an equal and opposite reaction. In re-action, a thrusting force is produced on the engine mount. The thrust accelerates the rocket as described by Newton's second law of motion.
