Answer:

TRUE

Explanation:

Uniform speed means the object will travel in such a way that it must cover equal distance in equal interval of time.

So after each equal interval of time the distance moved by the object is same then it is uniform speed but if the object travel unequal distance  in equal interval of time then it is representing the changing speed.

So here we can see that object covers 1 m distance in first interval of 1 s while in next 1 s interval from t= 1 to t = 2 it moved total distance of d = 5 - 1 = 4 m

In next interval of 1 s from t = 2 to t =3 it moved total distance of d = 25 - 5 = 20 m

So here we can say that speed of the object is changing

So above statement is TRUE

Velocity is:
sleet_krkn [62]

Answer:

d

Explanation:

Solution:-

- The Quantity of theory of money states:

                      M * V = P * Y

Where,

           M = Money supply

           V = Velocity of money exchange

           P = The price level

           Y = Real GDP

- By re-arranging the formula and solving for "V" we have:

                     V = P*Y / M

- The expression on right hand side increases if exchange of dollars increases.

For a railgun, determine the current required to accelerate a 1000kg space vehicle to earths escape velocity on 10km of track wi
Troyanec [42]

Answer:

the current is 15.68 × 10^{5} A

Explanation:

mass = 1000 kg

magnetic fied = 2T

rail separation = 2m

escape velocity is 11.2km/s  = 11.2 × 10^{3} m/s

distance = 10 km = 10^{4} m

to find out

determine the current

solution

we know force F = I×L×B

here I is current and L is rail separation and B is magnetic field

so F = I ×2×2  = 4 I

so

acceleration is a = \frac{F}{mass}

a =  \frac{4I}{1000} m/s²

so equation of motion

v²-u² = 2 a S

here u is initial velocity and S is distance and a is acceleration and v is final velocity

11.2 × 10^{3} - 0 = 2×  \frac{4I}{1000} × 10^{4}

solve we get I

I = 15.68 × 10^{5} A

so the current is 15.68 × 10^{5} A

A solenoid with 3,000.0 turns is 70.0 cm long. If its self-inductance is 25.0 mH, what is its radius? (The value of μ0 is 4π x 1
nevsk [136]

Answer:

A. 2.2*10^-2m

Explanation:

Using

Area = length x L/ uo xN²

So A = 0.7m * 25 x 10^-3H /( 4π x10^-7*

3000²)

A = 17.5*10^-3/ 1.13*10^-5

= 15.5*10^-2m²

Area= π r ²

15.5E-2/3.142 = r²

2.2*10^2m

Two Forces 20N and 50N act at a point and at an angle of 120 to each. Draw a force diagram for the system​
Cerrena [4.2K]

the resultant force is F=F1-F2.

F1 = 20 N, and F2 = 50 N

In this instance, two different resultant forces are feasible.

when the two are at an angle of A with one another.

See the outcome in case 1 of the image if both are facing the same way. if they are both facing the opposite directions. when both are at a zero-degree angle from one another If they are parallel to one another and moving in the same direction, the resultant force is F=F1+F2. If they are parallel but moving in the opposite direction, the resultant force is F=F1-F2.
