The relative density of gold is 19.3 it means the ratio obtained by dividing the density of gold by water at temp of 4 degree celcius is 19.3
Answer:
30N*s
Explanation:
Given the following data;
Force = 10N
Time = 3 seconds
To find the impulse;
Impulse = force * time
Substituting into the equation, we have;
Impulse = 10 * 3
Impulse = 30Ns
When ice melts, its temperature doesn't change ... ice at 32 degrees becomes water at 32 degrees.
When water boils, its temperature doesn't change ... water at 212 degrees becomes steam at 212 degrees.
The row that says both of these is row-D .
Answer:
24.3 m
Explanation:
Using the equation of motion
where s is the distance, u is initial velocity, t is time and a is acceleration
Substituting u for 6 m/s, t for 3 s, a for 1.4 m/s2 we obtain
Answer:
4 ft/s^2
Explanation:
If the velocity is 8ft/s after 2s then to find the acceleration you would use the formula:
sooooooooo
