Answer:
Time, t = 6.34 hours.
Explanation:
Velocity can be defined as the rate of change in displacement (distance) with time. Velocity is a vector quantity and as such it has both magnitude and direction.
Mathematically, velocity is given by the equation;
Therefore, making time the subject of formula;
Given the following data;
Displacement = 5200km
Average velocity = 820km/hr
Substituting into the equation, we have;
Time = 6.34 hours.
<em>Hence, it would take 6.34 hours for the airplane to reach its destination. </em>
Answer:
Voltage will be 100 volt
Explanation:
We have given current through the circuit i = 0.1 A
Power dissipated P = 10 W
We know that power dissipated through any resistive cirvuit is given by
, here i is current and R is resistance
So 
R =1000 ohm
Now according to ohm's law V = iR
So Voltage V = 0.1×1000 = 100 volt
Answer:
Iron
Explanation:
H = mc∅
Above equation can be used here to find the answer to the question. this equation gives us the relationship between the heat energy supplied to a material and the temperature difference that the material would go through according to its mass.
here H is the Heat energy supplied to the material. m is the mass of the material. c is the specific heat capacity of the material and ∅ is the temperature difference applied to the material. we are given that H= 337,500J , m = 50 kg and ∅ = 15 °C. so from the equation now we can calculate the value of c. after calculating c we can find the material because c is an unique value for a particular material. no two materials have the same c value.
c = 337500/(50*15)
c = 450 J/(kg°C) - Iron (google the heat capacity value to find the answer Iron)
