Answer:

The average acceleration is [tex]8\ m/s^2[/tex]

Explanation:

Uniform Acceleration

When an object varies its velocity at the same rate, the acceleration is constant.

The relation between the initial and final speeds is:

[tex]v_f=v_o+a.t[/tex]

Where:

vf  = Final speed

vo = Initial speed

a   = Constant acceleration

t   = Elapsed time

The acceleration can be calculated by solving for a:

[tex]\displaystyle a=\frac{v_f-v_o}{t}[/tex]

The Indy 500 race car increases its speed from vo=4 m/s to vf=36 m/s in t=4 s. Thus, the average acceleration is:

[tex]\displaystyle a=\frac{36-4}{4}=8\ m/s^2[/tex]

The average acceleration is [tex]8\ m/s^2[/tex]

Answer:

Q = 20900 [J]

Explanation:

We must use the following energy equation to determine heat transfer, based on specific heat, mass, and heat transfer.

[tex]Q=m*C_{p}*DT[/tex]

where:

Q = heat energy [J]

Cp = specific heat = 4184 [J/kg*K]

m = mass = 100 [g] = 0.1 [kg]

DT = temperature change = 50 [K]

[tex]Q= 0.1*4180*50\\Q=20900[J][/tex]

Answer:

d-135m

Explanation:

Answer:

Explanation:

Sphere B and sphere A are touching so they will act as a single body . A positively charged sphere C is brought near sphere B . So there will be induction of charge on sphere B and sphere A . Opposite charge will be induced on nearer sphere and same charge will be induced on distant sphere . Hence sphere B will be negatively charged and sphere A will be positively charged. The amount of charge induced on sphere B and A will be same and it will remain as long as sphere C is kept near sphere B . As soon as sphere C is removed , induced charges will also neutralize each other .

Answer:

the last one. gravitational force is stronger as objects get further apart

The false statement about gravity among the given choices is - D. The Law of Universal Gravitation states that the gravitational force is  stronger as objects get farther apart.

Gravity or the universal gravitational force is the force of attraction exerts between any two objects with mass in the universe. It is also exerted between the attraction of the earth's mass and bodies with mass near its surface.

Thus, The false statement about gravity among the given choices is - option D.

Answer:

The speed of sound in water is two times slower than that in air. Sound travels much faster in space than in water. Warmer water allows sound to travel faster so i think true

Explanation:

Explanation:

Average speed =total distance ÷ total time

speed = d ÷ t

d= 74400

t= 16

then,

speed = 74400÷16

=4650

Answer:

When the electrons jump to a higher energy state, they release energy as electromagnetic radiation, light.

Explanation:

When the solar wind gets past the magnetic field and travels towards the Earth, it runs into the atmosphere. As the protons and electrons from the solar wind hit the particles in the Earth's atmosphere, they release energy – and this is what causes the northern lights.

Answer:

The convex lens is shaped so that all light rays that enter it parallel to its axis cross one another at a single point on the opposite side of the lens.

Explanation:

Answer:

b. 1.1 m/s c. -1.1 m/s

Explanation:

b.

m x v=f x t

The mass is 10 kg

10 x v (equation for momentum) = f x t (impulse)

you would find the impulse by finding the area under the graph, and then dividing by the mass

So in this case:

10 x v = 11

then divide by the mass

v = 11/10

v= 1.1 m/s

c.

F x t = impulse

we are trying to find force (magnitude)

impulse/t = F

we said that in order for it to stop the impulse for b would be 11, so if thats the case it would be 11 but it would be negative because when going in a positive direction and suddenly stopping the direction changes.

-11/t = F

to find t all we need to do is find the amount of seconds between 10 and 20, that would be 10.

-11/10 = F

F= -1.1 m/s

Answer B:

The velocity of the box at 10 seconds is :

              m x v=f x t

Given Information :

Mass(m)=10kg

Therefore, the velocity of the box at 10 seconds is 1.1m/s.

Answer C:

The magnitude and direction of that force be :

F x t = impulse

To find t all we need to do is find the amount of seconds between 10 and 20, that would be 10.

The magnitude and direction of that force will be -1.1m/s.

Answer:

I hope the answer below helps :

Explanation:

Let the tension force be T in the rope.

The downward forces acting on the system of the boy and the box are the weight of the boy and the weight of the box.

The upward forces are T and T on each side of the rope.

As the system is in a static equilibrium:

[tex]T+T=(10+45)kg \\\\=>T=55kg[/tex]

or  55g or

Newtons=550N ,  if g=10m/s  

The forces acting on the boy are: Tension T, reaction from the weighing machine, and weight 45 g.  So,

Normal−reaction of the weighing machine :

[tex]45-T\\45-55\\=-10[/tex]

(i)  The weighing machine shows its normal reaction force as the weight of the person standing on it.  So weight displayed =-10kg.

(ii) Suppose the man pulls down the rope with a force F and the tension becomes T.

The forces acting downwards on the rope at the two ends are:  F, weights of man and the box.  The upward forces are Tension T on each side of rope.

The system being in equilibrium:

[tex]2T=F+45kgf+10kgf\\=F+55kgf\\=T=45kgf+\frac{F}{2}[/tex]

=>  Normal reaction force from the weighing machine on the man

N=45+F−T=-10kgf+F/2

If N is to become 45kgf, then  F has to be 55kgf or 550N

Answer:

The reading on the scale is 539 N.

Explanation:

The given parameters include;

The reading on the scale = weight of the boy + weight of the box

                                           = M₂g + M₁g

                                           = g(M₂ + M₁)

where;

The reading on the scale is calculated as follows;

W = 9.8(45 + 10)

W = 9.8(55)

W = 539 N

Thus, the reading on the scale is 539 N.

Answer: Cells have receptors because Receptors let the cell know when to let things in and out of the cell.

Explanation:

Cell receptors also called transmembrane receptors are proteins located on the surface of a cell (extracellularly) or inside the cell which receive signals that alters the functions of the cell. The functions of the cells which can be altered includes the alteration in gene transcription and the cell morphology.

Cell receptors are generally categorizes into the following groups:

--> Internal receptors

--> cell surface receptors

--> ion channel receptors

--> G protein coupled receptors

--> enzyme linked receptors

Interaction of cell membrane receptors with specific ligands that bonds to the receptors causes conformational changes in the receptor protein. This in turn, enzymatically activates the intracellular part of the protein or induces interactions between the receptor and the proteins in the cytoplasm that act as second messengers, thereby relaying the signal from the extracellular part of the receptor to the interior of the cell. This enables the cell to know when to let things in or out of it through the information conveyed.

Answer:

See the explanation below.

Explanation:

An example of renewable energy is wind energy, since the planet by means of pressure variations among other natural phenomena presents air currents that can rotate the propellers of energy-generating turbines. This energy is renewable because the wind is used as a source of this energy.

An example of non-renewable energy is oil as it has been formed by carbon-containing fossils that have remained in the Earth's layers for millions of years. It is a non-renewable source since the amount of oil is finished after its total extraction from one well and for the generation of another well will depend on geological processes that last millions of years.

Answer:

F = 36.956 N

Explanation:

The magnitude of the resultant force will be;

F = F1 × F2 × cosθ.

We are given;

F1 = 5 N

F2 = 8 N

The angle between the 2 forces is 45°

Thus, angle between each force and the vertical axis is 45/2 = 22.5°

F = 5 × 8 × cos 22.5

F = 40 × 0.9239

F = 36.956 N
