Well first you need to know the formula for the spring force. It’s -1/2k*d
K being the constant
D being the displacement
We can actually find the force on the spring by calculating the weight of the block. It would be mass multiplied by gravity, convert the grams to kilograms first tho.
600/1000 = 0.6kg
0.6kg * 9.8 m/s^2 = 5.88N
Now plug everything into the equation, also convert the centimeters to meters:
1.2/100 = 0.012 meters
5.88 = -1/2k*(0.012)
5.88 = k*(0.006)
We could drop the negative sign because we really just want the magnitude of the spring constant.
K = 980N
Answer:
What type of question is this?
Explanation:
Is this a true or false question?
The flashlight's beam will all be refracted towards a central axis. But, this is still dependent on the type of lens that is used for the said activity. The speed of light will vary depending whether the lens is a concave or a convex lens. The exit point of the light will always head towards the central axis.
Answer:
c. Momentum is the product of mass and velocity
e. Momentum is a vector quantity
g. Momentum has unit of kgm/s
Explanation:
Linear momentum P
P = m .v
m =mass
v=Velocity
If mass take in kg and velocity is in m/s then momentum p will be in kg.m/s.
1. momentum is the product of velocity and mass.
2.Momentum is a vector quantity.
3.Momentum have kg.m/s unit.
So the following option are correct.
c. Momentum is the product of mass and velocity
e. Momentum is a vector quantity
g. Momentum has unit of kgm/s.
Note-
1.Joule is the unit of energy.
2.One-half the product of mass and the square of the object's speed is known as kinetic energy.
