calculate the value of net force acting on given body?5N acting towards right & 15N force acting towards left on the brick.(draw fbd)
Answers
Answer:
The net force acting on the body is 10N directed to the left.
Explanation:
Magnitude of force to the right = 5N
Magnitude of force to the left = 15N
Net force acting on the object and in what direction;
Solution:
It is the vector sum of all forces acting on a body. This net force is the single force that will replace the forces acting on a body;
For the problem;
Net force = Force to the left + Force to the right
Let us take left to be negative and right to be positive;
Force to the left = -15N
Net force = -15N + 5N = -10N
The net force acting on the body is 10N directed to the left.

Explanation:
A 3 kg rubber block is resting on wet concrete. The coefficient of static friction is 0.3. What is the minimum force that must be applied to the block to make the block begin to accelerate?
Answers
Answer:
You would have to find the friction force of the rubber block which would be found with the equation of Normal force (mass*gravity) times cooeficient of friction which would give 8.82 N for the amount of friction and because you need more force than 8.82 N (assuming gravity is 9.8)
We need to find the frictional force of the rubber block. This is the normal force (mass × gravity) multiplied by the coefficient of friction, which gives us a friction quantity of 8.82N. This is because it requires a force greater than 8.82N (Gravity is 9.8)
What is coefficient of friction?Mathematically, = F/N, where F represents the frictional force and N represents the normal force. Because F and N are both measured in force units (such as Newtons or Pounds), the coefficient of friction is dimensionless.The friction coefficient is the ratio of the frictional force resisting movement of two contacting surfaces to the normal force pushing the two surfaces together.Both F and N are measured in units of force (such as Newtons or Pounds), so the coefficient of friction is dimensionless. The coefficient of friction has different values for static friction and sliding friction.In stiction, the frictional force resists the force applied to the object and the object remains stationary until the force of stiction is overcome. In kinetic friction, the frictional force opposes the motion of an object.To learn more about coefficient of friction, refer to:

When a wire moves through a magnetic field, an electric current is produced in the wire. Why does this phenomenon occur?
Answers
Answer:

Explanation:
Hope this helps
When a wire moves through a magnetic field, an electric current is produced in the wire, and the phenomenon to which this is referring is called electromagnetic induction, as presented in option A.
What is electromagnetic induction?A magnetic field is a region in space where a magnetic force can be detected, so when a wire moves through a magnetic field, the magnetic force exerted on the wire generates a voltage, and the voltage creates an electric current in the wire. This electromagnetic induction phenomenon occurs because of the movement of charged particles within the wire, and this phenomenon can be explained by Faraday's Law of Electromagnetic Induction.
Hence, an electric current is produced in the wire, and the phenomenon to which this is referring is called electromagnetic induction, as presented in option A.

B) In a baseball bat, effort force is smaller and is applied over a large distance, while the resistance force is smaller and is applied over a short distance.
C) In a baseball bat, effort force is larger and is applied over a short distance, while the resistance force is smaller and is applied over a long distance.
D) In a baseball bat, effort force is larger and is applied over a short distance, while the resistance force is smaller and is applied over a short distance.
Answer:
C) In a baseball bat, effort force is larger and is applied over a short distance, while the resistance force is smaller and is applied over a long distance.
Explanation:
The correct answer is option C. This is because unlike in a pry bar, the effort force when swinging a baseball bat is larger and it is applied over a short distance; and in return the resisting force is smaller and it's applied over a long distance.

Different Parts of an Electric Motor and Their Function
A simple motor has the following parts:
A power supply – mostly DC for a simple motor
Field Magnet – could be a permanent magnet or an electromagnet
An Armature or rotor
Commutator
Brushes
Axle
Power Source: A simple motor usually has a DC power source. It supplies power to the motor armature or field coils.
Commutator: It is the rotating interface of the armature coil with a stationary circuit.
Field Magnet: The magnetic field helps to produce a torque on the rotating armature coil by virtue of Fleming’s left-hand rule.
Armature Core: Holds the armature coil in place and provides mechanical support.
Armature Coil: It helps the motor to run.
Brushes: It is a device that conducts current between stationary wires and moving parts, most commonly the rotating shaft.
What Is The Working Principle of An Electric Motor?
The working of an electric motor is based on the fact that a current carrying conductor produces a magnetic field around it. To better understand, imagine the following situation.
Take two bar magnets and keep the poles facing each other with a small space in between. Now, take a small length of a conducting wire and make a loop. Keep this loop in between the space between the magnets such that it is still within the sphere of influence of the magnets. Now for the last bit. Connect the ends of the loop to battery terminals.
Once electricity flows through your simple circuit, you will notice that your loop “moves”. So why does this happen? The magnetic field of the magnets interferes with that produced due to electric current flowing in the conductor. Since the loop has become a magnet, one side of it will be attracted to the north pole of the magnet and the other to the south pole. This causes the loop to continuously rotate. This is the principle of working of electric motor.
A student hangs the south pole of a bar magnet near the north pole of

B. They move away from each other, then toward each other.
C. They move toward each other.
O D. They do not move.
Answers
When the south pole of a bar magnet is near the north pole of another bar magnet, they move toward each other. Therefore, option (C) is correct.
What is a magnet?A magnet can be described as a substance that creates a magnetic field and this magnetic field is the reason for the considerable properties of a magnet. The magnetic force pulls ferromagnetic materials, such as iron, cobalt, etc., and attracts or repels other magnetic substances.
A permanent magnet is composed of a material that is magnetized and produces its own magnetic field such material can be magnetized, and strongly attracted towards a magnet, is known as ferromagnetic, and contain the elements iron, and cobalt.
Each bar magnet possesses a set of North and South poles within them. The south pole of one magnet brings closer to the north pole of another magnet they attract each other and move toward each other.

the horizontal component of the golf ball's initial velocity is 47.92 m/s.
The given parameters;
initial velocity of the golf, v = 60 m/s
angle of projection of the golf, Ф = 37°
The horizontal component of the golf ball's initial velocity is calculated as follows;
[tex]v_0_x = v\times cos(\theta)\\\\[/tex]
[tex]v_0_x[/tex] = 60 m/s x cos (37)
[tex]v_0_x[/tex] = 60 m/s x 0.7986

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.
