The period is the temporal difference between two same points in consecutive waves
Answer:
24.24L
Explanation:
According to Boyle's law which states that "the volume of a given mass of gas at constant temperature is inversely proportional to its pressure". Mathematically, P = k/V where;
P is the pressure
V is the volume
k is the proportionality constant
PV = k
P1V1 = P2V2
P1 and P2 are initial and final pressure respectively
V1 and V2 are the initial and final volume respectively
Given P1 = 101kPa V1 = 6.0L, P2 = 25kPa V2 = ?
From the formula;
V2 = P1V1/P2
V2 = 101×6/25
V2 = 24.24L
The final volume for the gas is 24.24L
Potential Energy (P.E) = Mass x
Acceleration due to Gravity x Altitude. Putting this value in the above equation we get, Dimensional Formula of
Potential energy= M1L2T-2.
Answer:
distance = 6 m
Explanation:
- Distance is a scalar quantity (so, only magnitude, no direction), and it is calculated as the scalar sum of all the distances travelled by an object during its motion, regardless of the direction. So, in this problem, the distance covered by the pinecone is
d = 4 m + 2 m = 6 m
- Displacement is a vector quantity (magnitude+direction), and its magnitude is calculate as the distance in a straight line between the final position and the initial position of the object. In this case, the final position is 2 m west and the initial position is 0 m, so the displacement of the pinecone is
d = 2 m west - 0 m = 2 m west
So, a scalar quantity from this scenario is
distance = 6 m
Explanation:
It is given that,
Potential difference between the ends of a rod, V = 1.1 V
Length of the rod, l = 10 cm = 0.1 m
Area of cross section of the rod, 
The resistivity of graphite, 
(a) Let R is the resistance of the rod. It is given by :
So, the resistance of the rod is 0.833 ohms.
(b) Let I is the current flowing in the wire. It can be calculated using the Ohm's law as :
I = 1.32 A
(c) Let E is the electric field inside the rod. The electric field in terms of potential difference is given by :
E = 11 V/m
Hence, this is the required solution.
