Force applied on first mass = 2.8×3.9 = 10.92N
same force = 8.2×a
therefore
a = 10.92÷8.2 = 1.33ms-²
Answer: tortoise
Explanation:
Given the following :
Speed of tortoise = 1m/s
Speed of hare = 3m/s
Mass of hare = 5kg
Mass of tortoise = 20kg
Momentum = product of Mass and velocity
Momentum of hare = mass of hare × Velocity of hare
Momentum of hare = 5kg × 3m/s = 15kgm/s
Momentum of tortoise = mass of tortoise × Velocity of tortoise
Momentum of tortoise = 20kg × 1m/s = 20kgm/s
Therefore, tortoise has a greater momentum than hare.
Answer:
3.6 x 10⁻⁷ H
Explanation:
C = capacitance of the capacitor = 6.57 x 10⁻¹² F
L = inductance of the inductor = ?
f = frequency of broadcasting system = 103.9 MHz = 103.9 x 10⁶ Hz
frequency is given as
Inserting the values
L = 3.6 x 10⁻⁷ H
Answer:
Velocity ratio of a lever is 3 means distance travelled by effort is 3 times the distance travelled by the load. Efficiency of the pulley is 60%means 40% of the energy is lost in the machine due to the friction
