So the equation for weight is mass*gravity. For this example I will use 9.81 and 10.
67*10=670N
67*9.81=657.27N
Answer:
Average emf of coil is 58.4 V
Explanation:
Given :
No. of turns
Area of rectangular coil
Magnetic field T
Time of rotation sec
From the faraday's law,
Average induced emf =
But flux through coil is given by,
So we write above equation,
Average induced emf =
Where and ( angle between plane and magnetic field)
Average induced emf =
Average induced emf = V
Answer:
PE is an abbreviation for 'physical education'. Physical education is a course taught in school that focuses on developing physical fitness and the ability to perform and enjoy day-to-day physical activities with ease. Kids also develop skills necessary to participate in a wide range of activities, such as soccer, basketball, or swimming.

Answer:
1.53
Explanation:
α=Δl/(l Δt) here α is coefficient of linear expansion Δl is change in length l is original length andΔt is change in temperature
Δl=0.00174m , l=3.50m ,Δt=21-(-11-5)= 21+11.5 =32.5 ⁰C
α = 0.00174 / (3.50×32.5)
= 1.53×10^-5 ( ⁰C)^-1
