Explanation:
Boyle's law can be stated as the "volume of a fixed mass of a gas varies inversely as the pressure changes if the temperature is constant". It is mathematically expressed as;
P1 V1 = P2 V2
P1 is the initial pressure
V1 is the initial volume
P2 is the final pressure
V2 is the final volume
Charles's law states that the volume of a fixed mass of a gas varies directly as its absolute temperature if the pressure is constant.
It is mathematically expressed as;
= 
V and T are volume and temperature respectively
1 and 2 are the initial and final states
Answer:
180.28 km/h
Explanation:
Let north and south represent the positive and negative y axis and east and west represent the positive and negative x axis.
Given;
Velocity of wind vx= 100 km/s
Velocity of aircraft in still air vy = 150 km/s
The resultant velocity Vr is;
Vr = √(vx^2 + vy^2)
Vr = √(100^2 + 150^2)
Vr = 180.2775637731 km/h
Vr = 180.28 km/h
The spring formula:
Force = - (spring constant) · (distance stretched or squashed)
6 N = - (spring constant) · (33 cm)
= - (0.33 m) · (spring constant)
Spring constant = - (6 N) / (0.33 m)
= - 18.18 N/meter .
The negative signs means that the spring always wants to go in the
opposite direction from where you forced it, and return to its relaxed
length. If you stretch it, it tries to get shorter, and if you compress it,
it tries to get longer.
Answer:d
Explanation:
From Gauss law Electric field inside a surface is directly proportional to the charge enclosed in it.
Electric field inside a spherical shell is zero and hence there is no charge inside the spherical shell because q charge induces a -q charge on inside surface of spherical shell.
and to counter it there is q charge on the surface. So total charge outside the surface is Q+q
