A. True
B. False
Answer:
true
Explanation:
In a chemical reaction, the atoms and molecules that interact with each other are called reactants. In a chemical reaction, the atoms and molecules produced by the reaction are called products. In a chemical reaction, only the atoms present in the reactants can end up in the products.

When a traffic light turns from red to green, it takes much more force and time for a large truck to get going than it does a small, compact car. This is an example of which law of motion?
Answer:
First Law of Motion.
Explanation:
Inertia can be defined as the tendency of an object or a body to continue in its state of motion or remain at rest unless acted upon by an external force.
In physics, Sir Isaac Newton's First Law of Motion is known as Law of Inertia and it states that, an object or a physical body in motion will continue in its state of motion at continuous velocity (the same speed and direction) or, if at rest, will remain at rest unless acted upon by an external force.
The inertia of a physical object such as a truck is greatly dependent or influenced by its mass; the higher the quantity of matter in a truck, the greater will be its tendency to continuously remain at rest.
Hence, it would take much more force and time for a large truck to get going when the traffic light turns green than it does for a small, compact car. This is an example of the first law of motion.

0.125 C of charge flow out of a
5.00 V battery in 6.30 s. How
much resistance is attached to the
battery?
(Hint: What is the definition of current?)
(Unit = Ohm)
Answer:
Resistance = 252.53 Ohms
Explanation:
Given the following data;
Charge = 0.125 C
Voltage = 5 V
Time = 6.3 seconds
To find the resistance;
First of all, we would determine the current flowing through the battery;
Quantity of charge, Q = current * time
0.125 = current * 6.3
Current = 0.125/6.3
Current = 0.0198 A
Next, we find the resistance;
Resistance = voltage/current
Resistance = 5/0.0198
Resistance = 252.53 Ohms
You push a heavy crate. At first it doesn't move. You push harder, and it finally starts to move, but you still have to exert some force to keep it moving at a constant velocity. Explain.
Answer:
Explained below.
Explanation:
Newton's first law of motion states that an object will continue in its present state of rest or continue with constant speed in a straight line except it is acted upon by an external force.
For every object in motion or at rest there is a force of friction that tries to resist its motion or prevent it from moving with constant velocity.
Now, to push it from rest you will need to apply a force large enough to overcome its static friction. Now, after that initial motion, smaller forces will have to be applied to overcome what is called sliding friction that prevents the crate from sliding which will affect the constant velocity.

The velocity-time graph shows the motion of a truck. Find (i) its velocity , (ii) its acceleration and (iii) the distance covered by the cyclist in 15 seconds
no spam please and answer fast!
Answer:
(iii) 300m
Explanation:
(i) The velocity of the cyclist is constant with time, the rate of the change of the velocity with the time is zero. So the acceleration of the object will be zero.
(ii) According to the graph we observe that the cyclist is moving with the same velocity all the time, therefore, the velocity of the cyclist is [tex]20m/s^{-1}[/tex]
(iii) Apply the formula: (speed = velocity x time)
s = vt
s = [tex]20m/s^{-1}[/tex] x 15s
s = 300m

The first law of thermodynamics states that energy can neither be created nor destroyed. If this is true then why are we always looking for new sources of energy? Use the 2nd law of thermodynamics to answer this question.
Answer:
The second law of thermodynamics states in an isolated system, the entropy (the amount of thermal energy that cannot be converted into mechanical work, also known as the amount of disorder) always increases, therefore, an isolated system always require an external input (new sources) of energy for there to be orderliness or for the available energy of the system to remain constant or increase

Electric field strength depends on which of the following?
A
charge and distance
B
charge and mass
Coulomb constant and mass
D
Coulomb constant and radius
Electric field strength depends on charge and distance. The magnitude of the charge creating the field and the distance from the charge. The correct option is option (A).
The electric field strength describes the force experienced by a positive test charge placed in that electric field. The electric field strength depends on two factors: the magnitude of the charge creating the field and the distance from the charge.
Mathematically, the electric field strength is given by Coulomb's law:
E = k × (Q / r²),
where E is the electric field strength, k is the Coulomb constant (also known as the electrostatic constant), Q is the charge of the object creating the field, and r is the distance from the charge.
Therefore, the correct statement is that electric field strength depends on charge and distance. The correct option is option (A).

What distance did the boulder with a force of 24 Newtons travel if 240 joules of work was done on it?
d = 10 m
Explanation:
Work = force × distance
or
distance = work/force

= 10 m
Calculate the electrical energy use of the microwave in 120 V circuit has 7.5 A current flow, if it used for 0.05 hours
Answer:
162 KJ
Explanation:
The electrical energy can be calculated using the formula
E = V×I×t
Where, V= voltage = 120 V
I is current in ampere = 7.5 A and t is time in seconds
1 hour = 3600 sec
Therefore, 0.05 hour = 3600×0.05 = 180 sec
Substitute the values in above equation find electrical power
E = 120×7.5×180
= 162000 J
= 162 KJ
Therefore, the electrical energy use of the microwave = 162 KJ
