Answer:
They can do this with the help of mechanical power generated from the human muscle.
Explanation:
Since rescue workers engage in missions where it is usually difficult for them to get electrical energy to their devices and working tools, they could employ various materials that can be sourced around them to get energy to their tools. One of such is the mechanical power generated from the human body through squeezing and compressing.
Some green devices such as the dyno torch have been designed to be powered through this method. Repeated squeezing of its flywheel allows light to be generated.
Answer:
The sand absorbed more heat than the soil.

Answer:
Explanation:
Expression for emf induced = 1 /2 B n r²ω where B is magnetic field , r is radius of the coil and ω is angular velocity of rotation , n is no of turn .
ω = 2πf = 2π x 60 = 120 π ; where f is frequency of rotation .
emf induced = 1 /2 B r²x 120π x n
Putting the given values
10000 = .5 x B x .11² x 120 x 3.14 x 506
B = 8.67 T .
