Answer:
Acceleration is 12m/s^2
Explanation:
We have a resultant force of 10N to the right and a resultant of 4N to the left, since the tow forces are acting in opposite directions, we subtract the two forces to find the net force. The net force would be 6N to the right.
We also know that F=ma, where F=force, m=mass, and a=acceleration
we can rearrange the equation like this,
a=F/m
now we can plug in the known variables
a=6N/0.5kg
a=12m/s^2
Answer:
you need to know the wave length and frequency
Explanation:
it is because of the formula of the wave speed
Answer: Option (B) is the correct answer.
Explanation:
As we know that the temperature when the vapor pressure of liquid becomes equal to the atmospheric pressure surrounding the liquid. And, during this temperature liquid state of substance changes into vapor state.
But during this process of change in state of substance the temperature will cease to change for some time because unless and until all the liquid molecules do not convert into vapor state the temperature will not rise or change.
As the boiling point of water is 
so the temperature ceases to change from 
to 
.
Therefore, we can conclude that when heating water, during to temperature range the temperature will cease to change for some time.
Answer:
0.58 days is needed
Explanation:
Gravitational energy change from a height change equal to 8848 m for a mass of 53 kg is:
m*g*h = 53*9.81*8848 = 4600340.64 J = 4600.34 kJ
4.184 kJ are equivalent to 1 kcal, then:
4.184 kJ / 4600.34 kJ = 1 kcal / x kcal
x = 4600.34/4.184
x = 1099.5 kcal or large calories
The diet is 1910 kcal/day, then you need 1099.5/1910 = 0.58 days
