Two force vectors are oriented such that the angle between their directions is 38 degrees and they have the same magnitude. If t
1 answer:
Answer:
Sum of the forces will be equal to 3.479 N
Explanation:
We have given two same forces are oriented at an angle of 38°
Magnitude of each force is given
We have to find the sum of the forces
Sum of the forces will be equal to
So sum of the forces will be equal to
So sum of the force will be equal to 3.479 N

Answer:
Q = 200800 Joules.
Explanation:
Given the following data;
Mass = 4kg
Initial temperature = 30.0°C
Final temperature = 90.0°C
Specific heat capacity of glass = 837 J/kg°C
To find the quantity of heat absorbed;
Heat capacity is given by the formula;
Where;
Q represents the heat capacity or quantity of heat.
m represents the mass of an object.
c represents the specific heat capacity of water.
dt represents the change in temperature.
dt = T2 - T1
dt = 90 - 30
dt = 60°C
Substituting the values into the equation, we have;
Q = 200800 Joules.
Therefore, the amount of heat absorbed is 200800 Joules.
Answer:
Explanation:
As we know that resistance of one copper wire is given as
here we know that
now we have
now we know that such 17 resistors are connected in parallel so we have
Now if a single copper wire has same resistance then its diameter is D and it is given as
now from above two equations we have
now we have
