Explanation:

The velocity of an object is given by the rate of change of position as :

$v=\dfrac{dx}{dt}$

where

$\dfrac{dx}{dt}$ is the rate of change of velocity

From the position time graph of an object, the velocity of an object can be calculated using the slope of the graph. From the attached figure it is clear that the velocity is given by :

$m=\dfrac{x_2-x_1}{t_2-t_1}$

$m=\dfrac{20-10}{2-1}$

m = 10

i.e.

Velocity, v = 10 m/s

Hence, to calculate the velocity of an object the slope of the position vs time graph should be calculated

Answer:

Range is 62.5 metres

Explanation:

Time of flight

$t = \frac{2u \sin( \theta) }{g}$

for range, acceleration is zero

from second newton's equation:

$S = ut + \frac{1}{2} {at}^{2}$

but a = 0:

let range be x:

$x = ut \\ x = \frac{2 {u}^{2} \sin( \theta) }{g} \\ \\ x = \frac{ \{2 \times 25 {}^{2} \sin(30 \degree) \}}{10} \\ \\ x = 62.5 \: metres$

[ taken g to be 10 m/s² ]

How much current does it take to paralyze your muscles?

satela [25.4K]

Answer: Current needed, mA 20 Voltage needed, V AC 6

Explanation: An electric gradient (or field) can exist that is analogous to the situation described above for step and touch potentials. The situation is more complex to analyze in the water because a person in the water assumes different postures and orientations in 3 dimensions (up, down, and sideways—north, south, east, and west). The transthoracic and translimb voltages will vary as the person moves in relation to the orientation (direction) of the electric field.

Calculate the p.e. of a 5 kg mass when it is (i) 3 m, (ii) 6 m, above the ground. (g = 10 N/kg)

Mashcka [7]

Explanation:

P.E=MGH

(1) P.E=5×10(G)×3

= 150 kg m^/s^ ( ^ =sqaure)

(2) P.E=5×10×6

= 300 kg m^/s^

Hope it helps, just remember the formula u can solve any question regarding gravition of earth (P.E=Mgh)
