You can subtract the atomic number from the mass number in order to find the number of neutrons.
In this question, we know that mass= 10 kg = 10 x 1000 = 10,000 g
Distance = 1 m and Time = 0.5 s
Power = Force x Velocity
Velocity = Distance / Time = 1 m / 0.5 s = 2 m/s
So, Power = Force x (Distance / Time)
But Force= Mass x Acceleration due to gravity (g)
So, Force = 10 kg x 9.8 m/s
= 98
Therefore, Power =Force x Velocity= 98 x 2 =
196 W
Atomic number is the number of protons in an element. Mass number is the sum of both protons and neutrons. Thus, if you subtract 34 from 76 you’ll get the number of neutrons in said element.
76 - 34 = 42 neutrons
Answer:
a
Explanation:
Using fences.................................
Force(N)=150N
Area(A)=0.5m^2
Pressure(p)=?
We know that,
Pressure(p)=force/area
Or,p=150/0.5
Or,p=300
So,the pressure on the object is 300pascal.
