Answer:
J
Explanation:
= length of the rope connected = 13.4 m
= Angle made by the rope with the vertical = 72.4°
= height gained by the batman above the reference point
Height gained by the batman above the reference point is given as
= mass of batman = 89.5 kg
= acceleration due to gravity = 9.8 ms⁻²
Work done against gravity is same as the gravitational potential energy gained by batman and is given as
Inserting the above values
J
Answer:
10500 J/kg/*C
Explanation:
Quantity of heat required=mass of substance x specific heat capacity x change in temperature
Quantity of heat required=0.25 x 4200 x [30-20]
Quantity of heat required=0.25 x 4200 x 10
Quantity of heat required=10500 J/kg/*C
Answer: Approximately 65% from what i have learnt.
Urine is a liquid by-product of metabolism in humans and in many other animals. Urine flows from the kidneys through the ureters to the urinary bladder. Urination results in urine being excreted from the body through the urethra.
Answer:
Explanation:
We are given that
Distance between plates=d=2.2 cm=
Using 
We have to find the magnitude of E in the region between the plates.
We know that the electric field for parallel plates
Where 
Substitute the values
Hence, the magnitude of E in the region between the plates=
