Answer: Hypothesis

Explanation:

<em>For each experiment involving nanotechnology, Gerry  and Lena will test a </em><em><u>hypothesis.</u></em><em> </em>

<em />

Gerry and Lana will use the Scientific method for their nanotechnology research and a key stage in the scientific method is to come up with a Hypothesis.

A hypothesis gives a researcher direction because it is a theory that they formulate that is meant to explain the phenomenon that they are researching.

They will then test this theory to either disprove or approve it and in so doing will be able to come up with conclusions to the research. Gerry and Lana will therefore have to test a hypothesis for each experiment in order to continue with their research.

Need help with formula: H(t) = -16^2 + vt + s
Rom4ik [11]

<span> The equation is h(t) = at^2 + vt + d where a = acceleration of gravity = - 32.174 ft/sec^2 v = 25 feet/sec d = starting height = 0 and h(t) = 0 when the ball hits the ground. So, 0 = - 32.174t^2 + 25t + 0 You can use the quadratic formula on that if you want, or you can solve like this: 0 = - 32.174t^2 + 25t 0 = t ( -32.174t + 25) So, one solution of that is t = 0, corresponding to the initial time when the ball is kicked. The other time is: 25 = 32.174t t = 25/32.174 = 0.777 seconds or approximately 0.8 seconds.</span>

The water stream strikes the inclined surface of the cart. Determine the power produced by the stream if, due to rolling frictio
levacccp [35]

Answer

given,

constant speed of cart on right side = 2 m/s

diameter of nozzle = 50 mm = 0.05 m

discharge flow through nozzle = 0.04 m³

One-fourth of the discharge flows down the incline

three-fourths flows up the incline

Power = ?

Normal force i.e. Fn acting on the cart

F_n = \rho A (v - u)^2 sin \theta

v is the velocity of jet

Q = A V

v = \dfrac{0.04}{\dfrac{\pi}{4}d^2}

v= \dfrac{0.04}{\dfrac{\pi}{4}\times 0.05^2}

v = 20.37 m/s

u be the speed of cart assuming it to be u = 2 m/s

angle angle of inclination be 60°

now,

F_n = 1000 \times \dfrac{\pi}{4}\times 0.05^2\times (20.37 - 2)^2 sin 60^0

F n = 2295 N

now force along x direction

F_x = F_n sin 60^0

F_x = 2295 \times sin 60^0

F_x = 1987.52\ N

Power of the cart

P = F x v

P = 1987.52 x 20.37

P = 40485 watt

P = 40.5 kW
