Which is the force that slows a book sliding ona table

Answers

friction is the force. Friction is also what makes the heat when you rub your hands together really fast for a while, and without it, if you started running in an open field and then tried to stop, you would just keep going on forever until you collided with something

The force that slowed the book from sliding on a table is friction, friction is a type of force that causes things to slow down. In this the book slowed down because of friction.

Answer this please. thanks in advance!! please tel me a christmas tree lights are set up in series1. a set of lights has 50 bulbs what will be the voltage across each bulb?
show your working out.

Answers

If 50 identical light bulbs are connected in series across
a single power source, then the voltage across each bulb
is ( 1/50 ) of the voltage delivered by the power source.

Presuming that this tree is connected into a mains power source in the UK. The total output of the UK mains source is 230V. So if we share this voltage equally between 50 bulbs:
$230V / 50 = 4.6V$

I'm not 100 per cent sure this is correct though and different countries may have different mains power supplies. Hope it helps anyway.

EDIT: This also does not take into account resistance in the bulbs and wires but is all I can tell you from the information provided in the question.

Newton's laws of motion

Answers

1) The purse falls to the ground because of Newton’s first law, an object in motion stays in motion and an object at rest will stay at rest until an unbalanced force changes it. The first law includes inertia, which occurs when the object wants to continue to go forwards even when it’s been stopped. When Jane stops her car, the purse wants to keep going forward, therefore falling to the ground.

2) when you’re standing on the board, the board pushes up on you, while you/gravity is pushing downwards // when you jump down, the opposite force pushes upwards, allowing you to go up (jump)

3) Newton’s second law, A=F/M

5) 19.5 newtons

In the diagram, q1= +8.0 C, q2= +3.5 C, and q3 = -2.5 C. q1 to q2 is 0.10 m, q2 to q3 is 0.15 m. What is the net force on q2? Label sign for charges (+ or -). (Unit = N). pls help?

Answers

Answer:

f(t) = 28,7 [N]

Explanation: IMPORTANT NOTE: IN PROBLEM STATEMENT CHARGES ARE IN C (COULOMBS) AND IN THE DIAGRAM IN μC. WE ASSUME CHARGES ARE IN μC.

The net force on +q₂ is the sum of the force of +q₁ on +q₂ ( is a repulsion force since charges of equal sign repel each other ) and the force of -q₃ on +q₂ ( is an attraction force, opposite sign charges attract each other)

The two forces have the same direction to the right of charge q₂, we have to add them

Then

f(t) = f₁₂ + f₃₂

f₁₂ = K * ( q₁*q₂ ) / (0,1)²

q₁ = + 8 μC then q₁ = 8*10⁻⁶ C

q₂ = + 3,5 μC then q₂ = 3,5 *10⁻⁶ C

K = 9*10⁹ [ N*m² /C²]

f₁₂ = 9*10⁹ * 8*3,5*10⁻¹²/ 1*10⁻² [ N*m² /C²]* C*C/m²

f₁₂ = 252*10⁻¹ [N]

f₁₂ = 25,2 [N]

f₃₂ = 9*10⁹*3,5*10⁻⁶*2,5*10⁻⁶ /(0,15)²

f₃₂ = 78,75*10⁻³/ 2,25*10⁻²

f₃₂ = 35 *10⁻¹

f₃₂ = 3,5 [N]

f(t) = 28,7 [N]

Explanation:

During the course of trajectory the horizontal component of the velocity is; A) constant
B) increasing
C) decreasing
D) negative

Answers

The horizontal component of the velocity remains constant in a trajectory course.

Answer: A

Explanation:

The trajectory path is formed due to the gravitational pull acting on the object thrown from some point either upward or downward.

As it is known that the velocity is divided into horizontal and vertical component, the vertical component of the velocity of the object thrown will be mainly influenced by the gravitational pull as it acting in vertical direction only.

So the vertical component of the object following a trajectory path will be changing at a rate of 9.8 m/s2 which is the acceleration due to gravity.

On the other hand, the horizontal component of the velocity will remain constant in order to maintain the law of conservation of energy.
