u have not displayed the question fella but i can guess the answer

Explanation:

the answer is (i)

because the current in a circuit is always directly proportional to its voltage thus making it to make a straight line in its graph

zhannawk [14.2K]

Answer:

F = 5000 [N] or 5 [kN]

Explanation:

In order to solve this problem we must take into account Newton's second law, which tells us that the sum of all forces applied on a body must be equal to the product of the mass of the body by its acceleration.

F = m*a

where:

F = force [N]

m = mass = 1000 [kg]

a = acceleration = 5 [m/s^2]

F = (1000*5)

F = 5000 [N] or 5 [kN]

In the film, 2001: A Space Odyssey, astronauts travel through space and experience artificial gravity created by a spinning, cyl

katrin2010 [14]

Artificial gravity is created by rotating the cylinder

So here we can say that the acceleration is due to centripetal acceleration

So here we know that the formula of centripetal acceleration is given by

$a_c = \frac{v^2}{R}$

so here we know that

$a_c = 9.8 m/s^2$

$v = 30.9 m/s$

now we will plug in all values

$9.8 = \frac{30.9^2}{R}$

$R = \frac{30.9^2}{9.8}$

$R = 97.43 m$

So above is the radius of the cylinder

Now to find the diameter

$d = 2R$

$d = 2*97.43$

$d = 194.8 m$

so its diameter is 194.8 m

A particle moving at 10 m/s along the x-axis collides elastically with another particle moving at 5.0 m/s in the same direction

drek231 [11]

Explanation:

It is given that,

Velocity of particle 1, u₁ = 10 m/s

Velocity of particle 2, u₂ = 5 m/s

Let v₁ and v₂ are the final speed of both particles after the collision. Applying the conservation of momentum as :

$mu_1+mu_2=mv_1+mv_2$
