The resulting velocity of the object is 40 m/s.
In this scenario, a 0.07 kg arrow is fired at an object of mass 4.0 kg, which is initially at rest on a frictionless surface. The speed of the arrow before the collision is 90 m/s. After the collision, the arrow emerges with a speed of 60 m/s.
To calculate the resulting velocity of the object, we can use the conservation of momentum. Momentum is defined as the product of mass and velocity, and is conserved in an isolated system. Using the equation:
(m1v1 + m2v2) = (m1v1' + m2v2')
We can solve for the velocity of the object after the collision. Substituting the given values, we get:
(0.07*90) + (4.0*0) = (0.07*60) + (4.0*v2')
Solving for v2', we get:
v2' = 40 m/s
Therefore, the resulting velocity of the object is 40 m/s.

Calculate the weight of the box
what are the givens
what is the equation
how to solve
Then draw a free body diagram that includes all the forces acting on the box with labels numbers and units i (if possible)
what is the net force acting on the box
finally what is the acceleration of the box what are the givens, equation and how to solve
Answer:
To summarize:
The weight of the box is 123.88 NThe net force acting on the box is 17 N (to the right)The acceleration of the box is 1.35 m/s^2 (to the right)
And the Free Body Diagram is:
[tex][box]^||54 N (applied force)|||v37 N (friction)[/tex]
Explanation:
Given:
Mass of the box: 12.6 kgApplied force: 54 NFrictional force opposing motion: 37 NTo calculate the weight of the box:
The weight of an object is equal to its mass multiplied by the acceleration due to gravity (g).The weight of the box is 12.6 kg * 9.8 m/s^2 = 123.88 N (approx).Free Body Diagram:
[tex][box]^||54 N (applied force)|||v37 N (friction)[/tex]
Net force acting on the box:
The net force is the vector sum of all the forces acting on the object.In this case, the net force is 54 N - 37 N = 17 N (to the right).To calculate the acceleration of the box:
The acceleration of an object is equal to the net force acting on it divided by its mass.The acceleration of the box is 17 N / 12.6 kg = 1.35 m/s^2 (to the right).consider a point 0.5 m above the midpoint of the two charges. as you can verify by removing one of the positive charges, the electric field due to only one of the positive charges is about 18 v/m . what is the magnitude of the total electric field due to both charges at this location? consider a point 0.5 above the midpoint of the two charges. as you can verify by removing one of the positive charges, the electric field due to only one of the positive charges is about 18 . what is the magnitude of the total electric field due to both charges at this location? 16 v/m 25 v/m zero 36 v/m
The magnitude of the total electric field due to both charges at this location is 36 v/m. Thus option D is the answer.
This is because the electric field due to each positive charge is 18 v/m, and since the charges are of the same magnitude and opposite in sign, the fields due to each charge will cancel each other out.
The electric field due to a point charge is given by the formula [tex]E = k*Q/r^2,[/tex]where k is the Coulomb constant, Q is the charge, and r is the distance from the point charge. Since the charges are equal and opposite, the net electric field at the point in question is zero.
So, the total electric field due to both charges is the vector sum of the fields due to each charge. Since the charges are equal and opposite, and the point is located in the same distance from both charges, the fields due to each charge will be in the same direction and thus they add up and the total electric field is twice 18 v/m which is 36 v/m.

Under what conditions the torque due to an applied force is zero class 11?
When there is no net torque acting on the body, it is considered to be in rotational equilibrium. In this case, the angular velocity of the body is constant.
Therefore, torque is equal to zero. In other words, torque is zero when the axis of rotation is crossed by the force.
In physics and mechanics, torque is the spinning equivalent of force. Another name for it is the moment of force. It serves as an example of how a force can alter a body's rotational motion.
For instance, no rotation will occur if a force is applied to the door's line. On the other hand, applying a force of a specific size at a right angle to the door's outside edge is the most effective technique to make it rotate. It does so because it rotates as a result of the torque this force produces.

The mass of the liquid in the vat of 1 m diameter and 2 m deep is 2435.54 kg.
Suppose we consider p to be the density of the liquid;
Then the pressure situated at the bottom with a depth (h) of the vat can now be: P = P0 + pgh
where; po = atmospheric pressure.
P-P0 = pgh
p = (P-P0)/gh
We know that: density(p) = Mass/ Volume
The mass of the liquid in the vat can be determined by the formula:
m=pV where; p = (P-P0)/gh
Then; m = (p = (P-P0)/gh) * Area(A) * h
m =(p = (P-P0)/g) *A
m = (p = (P-P0)/g)* Pie(d/1)^2
replacing the values, we have:
m =(1.3 atm - 1.0 atm)/9.8*Pie(1.0/2)^2
m= (1.3 atm - 1.0 atm)/9.8*(1.013 * 10^5)/1*Pie(1.0/2)^2

Friction converts some of the kinetic energy of an object into heat energy. Another way that an object can lose kinetic energy is through air resistance, which occurs when an object is moving through a fluid or gas. Air resistance also converts some of the kinetic energy of an object into heat energy. Another way an object can lose kinetic energy is through collisions. When two objects collide, some of the kinetic energy of the objects is transferred to the other object. If the collision is inelastic, the total kinetic energy of the objects is not conserved, and some of it is converted into other forms of energy, such as heat or sound. Finally, an object can lose kinetic energy due to external forces, such as gravity. When an object is thrown upward, it initially has kinetic energy, but as it rises, it loses kinetic energy as it slows down and eventually comes to a stop at its maximum height. In summary, when an object loses kinetic energy, it means that it is slowing down or stopping. There are several ways that an object can lose kinetic energy, such as through friction, air resistance, collisions, and external forces.
