Question

Please answer me

Give all Science formulas

Answer 1

1

To find....

....use this formula

Speed

where v is speed in metres per second, s is distance in metres, and t is time in seconds

Velocity

where v is velocity in metres per second, d is displacement in metres, and t is time in seconds

Acceleration

where a is acceleration in m/s

2

, v is change in velocity in metres per second, and t is time in seconds

Weight

W = mgwhere W is weight, m is mass in kilograms and g is acceleration due to gravity in m/s2(on Earth, acceleration due to gravity is approximately 9.8 m/s2)

Force

F = mawhere F is force in newtons, m is mass in kilograms, and a is acceleration in m/s2

Work Done

W = Fswhere W is work in joules, F is force in newtons, and s is the distance over which the force is applied

Gravitational Potential Energy

GPE = mgh where GPE is gravitational potential energy in joules, m is mass in kilograms, g is the acceleration due to gravity in m/s2, and h is height in metres (on Earth, acceleration due to gravity is approximately 9.8 m/s2)

Elastic Potential Energy

EPE =

kx

2

where EPE is elastic potential energy in joules, k is the spring constant of the object, and x is the length of extension or compression in metres

Power

P = Wtwhere P is power in watts, W is work in joules, and t is time in seconds

Mechanical Advantage

where MA is the mechanical advantage and the load and effort are measured in newtons

or

where both distances are measured in metres in a first or second class lever

Answer 2

which class ?

i m giving for class 10 physics

$v = \frac{i}{r} \\ q = n \times e \\ i = \frac{q}{t} \\ v = \frac{w}{q} \\ power = work \: done \times time \\ h = {i}^{2} rt = vit = \frac{ {v}^{2} }{r} \times t \\ for \: power \: divide \: all \: heat \: formulas \: by \: t \\ \\ mirrors \: formula \: \frac{1}{f} = \frac{1}{v} + \frac{1}{u} \\ lens \: formula = \frac{1}{f} = \frac{1}{v} - \frac{1}{u} \\ magnification \: of \: mirror = \frac{ - v}{u} = \frac{height \: of \: image}{heigt of \: object} \\ magnification \: of \: lens = \frac{v}{u} = \frac{hi}{ho} \\ p = \frac{1}{f}$
