Answer:
The meter, symbol m, is the SI unit of length. It is defined by taking the fixed numerical value of the speed of light in vacuum c to be 299 792 458 when expressed in the unit m s-1, where the second is defined in terms of ΔνCs. The kilogram, symbol kg, is the SI unit of mass.

Answer:
There is no way of knowing the phase composition without more information
Explanation:
For equilibrium to be established quantity of heat loss by the water must equal to the quantity of heat gain by the ice since the container is insulated which rules out loss of heat to the environment. To be able to the determine the phases present we need the temperature of the water as well as the temperature of the ice, mass of the water present and the mass of the ice . These two are not given, we therefore do not have enough information to determine the phases present even when we can easily get the values of specific heat capacity and latent heat of fusion.

Answer:
Explanation:
<u>Frictional Force
</u>
When the car is moving along the curve, it receives a force that tries to take it from the road. It's called centripetal force and the formula to compute it is:
The centripetal acceleration a_c is computed as
Where v is the tangent speed of the car and r is the radius of curvature. Replacing the formula into the first one
For the car to keep on the track, the friction must have the exact same value of the centripetal force and balance the forces. The friction force is computed as
The normal force N is equal to the weight of the car, thus
Equating both forces
Simplifying
Substituting the values
