What is the electric potential at a distance of 1.2 m from a 7.5 UC point charge?
5.6 x 104 v
8.1 x 104 V
5.6 % 1010 V
8.1 x 1010 V

Answer:

Hmmm

Explanation:

Here what I know... If a function gives the position of something as a function of time, the first derivative gives its velocity, and the second derivative gives its acceleration. So, you differentiate position to get velocity, and you differentiate velocity to get acceleration. where t is in seconds and H(t) is in inches.

Answer is D

Ndmdjdndbdjdkskd

The impulse acting on an object and the impact time, the equation F= I / Δt can be used to calculate the force applied to an object, therefore the correct answer is D.

The product of the average applied force and the time for which it is exerted is known as an impulse.

the mathematical relation for impulse is

Impulse  = F * Δt

where F represents the force applied and Δt represents the time for which the force is applied

Thus, the correct equation that can be used to calculate the force applied to an object is F = I /Δt and the correct option is D.

Answer:

Global climate is determined depending on the amount of energy given from the sun to the certain area.

Example:

When it is Summer, (June, July) the Northern Hemisphere receives the most light and heat because it is tilted toward the sun.

Answer:

P = 450 J

Explanation:

Given that,

Mass of a child, m = 18 kg

The vertical distance from the top to the bottom of the slide is 2.5 metres.

The Gravitational field strength = 10 N/kg

We need to find the decrease in gravitational potential energy of the child sliding from the  top to the bottom of the slide.

The formula for the gravitational potential energy is given by :

P = mgh

Substituting all the values,

P = 18 kg × 10 m/s² × 2.5 m

P = 450 J

Hence, the decrease in gravitational potential energy is 450 J.

Answer:

where is the figure?

Explanation:

Answer:

At the midpoint of the line joining the two equal charges

Explanation:

The midpoint of the line joining the two equal charges has equal distance from each charge. Since the charges are at x = a and x = -a, at the midpoint of the line joining the two equal charges, the magnitude of the electric field experienced as a result of each charge is the same. But these two fields are in opposite direction, hence the net resulting electric field would be equal to zero.

Explanation:

Answer:

A blackbody, or Planckian radiator, is a cavity within a heated material from which heat cannot escape. No matter what the material, the walls of the cavity exhibit a characteristic spectral emission, which is a function of its temperature.

Example:

Emission from a blackbody is temperature dependent and at high temperature, a blackbody will emit a spectrum of photon energies that span the visible range, and therefore it will appear white. The Sun is an example of a high-temperature blackbody.

Answer:

i. The velocity ratio of the plane is 4.

ii. The mechanical advantage of the plane is 3.

Explanation:

i. The velocity ratio (VR) of an inclined plane is ratio of its length to the height. It is given as;

VR = [tex]\frac{length of the plane}{height}[/tex] = [tex]\frac{l}{h}[/tex]

Given: l = 12 m, L = 600 N, E = 200 N, h = 3 m.

So that,

VR = [tex]\frac{12}{3}[/tex]

     = 4

The velocity ratio of the plane is 4.

ii. Mechanical advantage (MA) expresses the relationship between the load overcome to effort applied.

MA = [tex]\frac{Load}{Effort}[/tex] = [tex]\frac{L}{E}[/tex]

      = [tex]\frac{600}{200}[/tex]

      = 3

The mechanical advantage of the plane is 3.

Therefore, the velocity ratio of the inclined plane is 4, and its mechanical advantage is 3.

Answer:

Q = 41800[J]

Explanation:

These types of problems can be solved using the following heat transfer equation for quarps that increase or decrease their temperature as a function of mass.

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

where:

Q = Heat absorbed [J]

m = mass = 2 [kg]

DT = temperature change = 5 [°C]

Cp = specific heat of the water = 4180 [J/kg*°C]

[tex]Q=2*4180*5\\Q=41800[J][/tex]

Units of energy (Joules) [J]

Explanation:

The unit of volume derived from SI units(1) is the cubic meter, m3.

Chemists in a laboratory usually deal with much smaller volumes than cubic meters and the metric but non-SI units of liter or litre (L) and milliliter or millilitre (mL or ml) are in common use.

In 1964 the litre was redefined as being equal to exactly 1 cubic decimetre:

1 L = 1 dm3

So 1 milliltre = 1 cubic centimetre

1 mL = 1 cm3 (= 1cc)

Other metric units of measuring volume are given in the table below:

large volume → → → → → → → → → → small volume

Answer:

0.8J

Explanation:

Given parameters:

Force  = 20N

Compression  = 0.08m

Unknown:

Spring constant  = ?

Elastic potential energy  = ?

Solution:

To solve this problem, we use the expression below:

           F = k e

F is the force

k is the spring constant

e is the compression

             20  = k x 0.08

              k  = 250N/m

Elastic potential energy;

       EPE  = [tex]\frac{1}{2}[/tex] k e²    =  [tex]\frac{1}{2}[/tex]  x 250 x 0.08²

 Elastic potential energy = 0.8J
