I got this same question, and it worked for me! Hope this helps <3
A boy is pulling a 150 kg crate with a force of 1150 N. If the crate experiences a frictional force of 490 N, find:
a) The acceleration of the crate.
b) The normal force acting on the crate.
First, let's find the resultant, and applicate 2nd law of Newton using the resultant, so:
R = ma
F - Ff = ma
Data:
F = Force = 1150 N
Ff = Friction force = 490 N
m = Mass = 150 kg
a = Aceleraction = ?
Replacing according our data:
1150 N - 490 N = 150 kg * a
660 N = 150 kg * a
660 N / 150 kg = a
a = 4,4 m/s² ← Aceleration of the object
For the normal force:The normal force IS NOT the resultant force, the normal force's the force between the ground and the object, in another words, is the weight of the object, and for the weight:
w = mg
w = 150 kg * 10 m/s²
w = 1500 N ← Normal force between object and ground.

Which diagram shows a situation that would not produce an electric current in the wire?
Answer:B
Explanation:
A P E X
The diagram in which there is no current in the electric wire is B, the reason behind that it is not connected with the battery.
What is Electrical energy?When put in an electromagnetic field, charged matter experiences a force due to the fundamental property of electric charge. Positive or negative electrical ions are possible.
When two charge are in opposition to one another, they repel one another. The term "neutral" refers to an object has no net charge. The early understanding of the way charged particles interact is now referred to as classical electrodynamics, and it is still true for issues that do not demand for taking into account quant phenomena.
Electrical charge is a preserved attribute, meaning that the net charged of an isolated system—that is, the sum of the positive and negative charges—cannot change. Particles at the subatomic level carry an electric charge.
The second diagram from the option will have no current in it because the wires are not connected with the battery, so the flow of current will not take place.

Answer:
Option B 400meters
Explanation:
What is displacement
Displacement is a vector whose length is the shortest distance from the initial to the final position of a point P undergoing
Given data
number of laps = 2
length of lap= 400meters
Since after every one lap she returns to her initial position ]
the displacement is 400meters

A 15 kg block is sliding along a frictionless surface and strikes a 10 kg ball at rest. What is the collision of the blocks after the collision if it is an inelastic collision?
Answer:
v = 0.6 v₁
Explanation:
This is an exercise in collisions, let's start by defining a system formed by the two bodies, so that the forces during the collisions have been internal and the momentum is preserved.
Instant starts. Before the crash
p₀ = M v₁ + m 0
Final moment. After the crash
[tex]p_{f}[/tex] = (M + m) v
how momentum is conserved
p₀ = p_{f}
M v₁ = (M + m) v
v = [tex]\frac{M}{M+m} v_{1}[/tex]
let's calculate
v = [tex]\frac{15}{15+10} v_{1}[/tex]
v = 0.6 v₁
incline plane is given length 12m,load 600 newton,effort 200 Newton, Height 3 metre find its velocity ratio and mechanical advantage
Answer:
i. The velocity ratio of the plane is 4.
ii. The mechanical advantage of the plane is 3.
Explanation:
i. The velocity ratio (VR) of an inclined plane is ratio of its length to the height. It is given as;
VR = [tex]\frac{length of the plane}{height}[/tex] = [tex]\frac{l}{h}[/tex]
Given: l = 12 m, L = 600 N, E = 200 N, h = 3 m.
So that,
VR = [tex]\frac{12}{3}[/tex]
= 4
The velocity ratio of the plane is 4.
ii. Mechanical advantage (MA) expresses the relationship between the load overcome to effort applied.
MA = [tex]\frac{Load}{Effort}[/tex] = [tex]\frac{L}{E}[/tex]
= [tex]\frac{600}{200}[/tex]
= 3
The mechanical advantage of the plane is 3.
Therefore, the velocity ratio of the inclined plane is 4, and its mechanical advantage is 3.

A laser beam is directed at the Moon, 380,000 km from the Earth. The beam diverges at an angle of \thetaθ of 0.8 x 10-5 rad. What diameter spot, in m, will it make on the Moon?
Answer:
3040 m
Explanation:
The formula to apply here is ;
d=∅*r where
d is the diameter of the spot , ?
∅ is angle of divergence in radians, = 0.8 * 10⁻⁵rad
r is distance of Moon from Earth, =380,000 km
Applying the formula as;
d=∅*r
d= {0.8 *10⁻⁵} * 380,000 * 1000
d= 3040 m
Josh is playing pool. During his shot, an orange billiard ball with a momentum of 165 g · m/s hits a green billiard ball at rest. After the collision, the orange billiard ball continues in the same direction with a momentum of 60 g · m/s. What is the momentum of the green ball right after the collision?
Answer:
105 g.m/s
Explanation:
The law of conservation of momemtum states that initial momemtum is equal to final momentum.
initial momentum of orange ball = 165 g.m/s
initial momentum of green ball = 0 g.m/s
final momentum of orange ball = 60 g.m/s
final momentum of green ball = x
165+0=60+x
⇒x = 165-60= 105 g.m/s
the momentum of the green ball right after the collision =105 g.m/s

What current passes through a 1 kW heater with 25 V across it?
Answer:The voltage V in volts (V) is equal to the current I in amps (A) times the resistance R in ohms (Ω): V (V) = I (A) × R (Ω) The power P in watts (W) is equal to the voltage V in volts (V) times the current I in amps (A): P (W) = V (V) × I (A) AC Ohm's law calculator.
Explanation:
40 ampere current passes through a 1 kW heater with 25 Voltage across it.
What is voltage?The difference in electric potential between two places is known as voltage, often referred to as electric pressure, electric tension, or potential difference. It relates to the amount of labor required to transfer a test charge between two places in a static electric field.
Given that power of the source is 1 kW and voltage is 25 V
current is given as,
Power = Voltage*Current
1kW = 25*Current
Current = 1000/25 = 40 ampere.

A. 350 m/s
B. 9,800 m/s
C. 450 m/s
D. 13 m/s
Answer:
C. 450
it should be right
The new speed of sound wave is 450 m/s. Hence, option (C) is correct.
What is sound wave?A sound wave is the pattern of disruption brought on by the movement of energy moving through a medium as it propagates away from the source of the sound (such as air, water, or any other liquid or solid matter).
Pressure waves are produced when an object vibrates, such as a ringing phone, and these waves are known as sound waves.
Frequency of sound wave is = 16 Hz.
Wavelength of the sound wave is = 28 m.
Hence, new speed of sound wave is = 16 × 28 meter/second
= 448 meter/second
