Answer:
work
Explanation:
it is a scalar quantity. it is equal to product of force and distance if the direction of motion is in direction of force in straight line
Answer:
Low specific heat values
Explanation:
Metals are generally known to have very low specific heat values because they are good conductors. It simply implies that it takes very little heat energy to cause a rise in temperature of metals compared to other substances.
- Specific heat capacity is the amount of heat required to raise the temperature of a unit mass of a substance by 1°C.
A material that can conduct heat i.e allows it to flow readily and thereby, will require little amount of heat.
Answer:
Explanation:
Given that the velocity of the river is 1.50m/s due east.
The velocity of the boat with respect to the river is 10.0 m/s due north .
The width of the river is 325 m.
Note that the velocity of the boat will help in crossing the river.
Hence, speed = distance/time
Speed = 10.0 m/s
Distance = 325 m
Time = ?
10 = 325/time
Time = 325/10
Time = 32.5s
Hence in 32.5s the horizontal distance traveled by boat will be
= 1.50m/s × 32.5s
= 48.75m
Explanation:
Mass = density × volume
m = (0.7 g/mL) × (40 mL)
m = 28 g
Rounding to 1 significant figure, the student should weigh out 30 grams of diethylamine.
