Hi there!

Using the equation for current:

[tex]I = \frac{\Delta Q}{\Delta t}[/tex]

I = Current (A)
Q = Charge (C)
t = time (s)

Therefore, the current is equivalent to the amount of charge passing through a wire over a given time interval.

We can plug in the given values and solve.

[tex]I = \frac{1200}{200} = \boxed{6 A}[/tex]

A wool sweater worn under a cotton jacket produces more static charges.

Static charge is an imbalance of electric charges within or on the surface of a material or between materials.

Static charges can be produced by two materials together (friction method).

A wool sweater worn under a cotton jacket (in the absence of lubricant like water) creates friction which enables more static charge to be produced.

Thus, a wool sweater worn under a cotton jacket produces more static charges.

Explanation:

We can see from the calculations that the acceleration of the proton is 1.43 * 10^7 ms-2.

Acceleration is the rate of change of velocity with time. We know that the magnetic force is obtained by;

F = qvB

q= 1.6 * 10^-19 C

v = 365 m/s

B =  4.10*10^-5 T

F = 1.6 * 10^-19 C * 365 m/s *  4.10*10^-5 T

F = 2.39 * 10^-20 N

Recall that the mass of the proton is 1.67 × 10−27 kg hence

a = F/m = 2.39 * 10^-20 N/1.67 × 10−27 kg  = 1.43 * 10^7 ms-2

You included all the stages of matter and described each of them. You're outlining their properties and you've created a clear diagram (and by diagram I mean chart) of solids, liquids, and gas.

Answer:-2.86*10⁻⁴

Explanation: Use the equation change in volume = (change in pressure * original volume) / Bulks Modulus. ΔV = (-Δp*V₀) / B

Plugging in your numbers, you should get ΔV = (-2.29*10⁷*1) / (8*10¹⁰) = -2.86*10⁻⁴

ΔP = P₂-P₁  ----> ΔP = 2.30*10⁷ - 1.00*10⁵ = 2.29*10⁷

Answer:

I can help, but

Explanation:

Where is the question?

Given the diagram provided, we can confirm that the object will accelerate in a downward direction.

The free-body diagram shows us the forces that are acting on this object. Through this diagram, we can see that the forces on the left and right of the object are balanced, meaning that there will not have movement in either of these directions.

The diagram shows that the downward force being applied is not balanced by an opposite force, so the object will accelerate in this direction.

Therefore, we can confirm that object will accelerate in a downward direction due to its downward force not being balanced by an opposing force.

Answer:

45.5 m

Explanation:

m = 2 kg, h = 20 m, E = 500 J, radius of earth = R, mass of earth = M

find the new height H

at h, the potential energy = -GMm/(R + h)

at H, the potential energy = -GMm/(R + H)

increase of the potential energy

= [-GMm/(R + H)] - [-GMm(R + h)]

= GMm[1/(R + h) - 1/(R + H)] = E

1/(R + h) - 1/(R + H) = E/(GMm)

(H - h)/[(R + H)(R + h)] = E/(GMm)

R + h ≈ R, R + H ≈ R

so (H - h)/R² = E/(GMm)

H - h = ER²/(GMm)

note GM/R² = g = 9.81 m/s²

so H - h = E/(mg)

H = h + E/(mg) = 20 + 500/(2*9.81) = 45.5 m

Answer:

Given:

m=1000kg

F=8000 N

u=32m/s

v=0m/s

Required:

T=?

Solution:

F=m × a

8000N = 1000kg × a

a = 8m/s^2

Since it's deceleration -8m/s^2

a= v - u / t

-8m/s^2 = 0 - 32m/s / T

T = 4 s

Hence the car takes 4sec to stop

Please follow me

The stopping time of the car is equal to 4 seconds.

Speed is defined as the ratio of the time distance travelled by the body to the time taken by the body to cover the distance. Speed is the ratio of the distance travelled by time. The unit of speed in miles per hour.

Given that,

m=1000kg

F=8000 N

u=32m/s

v=0m/s

The acceleration will be calculated by the formula below,

F = m × a

8000N = 1000kg × a

a = 8 m/s²

Since its deceleration -8m/s². The time taken is calculated by the formula,

a= v - u / t

-8= (0 - 32 ) / t

t = 32 / 8

t = 4 seconds

Therefore, the stopping time of the car is equal to 4 seconds.

#7 : Frequency

The answers to the questions are as follows :

Position time graphs are motion graphs that show the change in an object position in relation to time traveled, while a displacement time graph shows if an object is going backwards or forward and unlike distance, she does not consider the direction of movement of an object.

Motion graphs are used for the presentation of the motion of objects visually.
