Answer:
the rock will sink. this is because it is more dense than water
In the cytoplasm, molecules of Glucose are broken down to smaller molecules hence releasing mechanical energy during a process called called respiration or simply 'breathing process' in Physics realm.
Answer:
increase the resistance of the bulb
Explanation:
In a simple circuit the power dissipated in a light bulb is proportional to the product of the voltage and the current
P = i V
Besides the voltage is
V = i R
P = i² R
Therefore, a simple method to decrease the power dissipated in a bulb to increase the resistance of the bulb, for this a series resistance is placed in the circuit.
Consequently the correct answer is increase the resistance of the bulb
Answer:
Both cyclists have a displacement (vector) of 546.41 m
V(velocity) = 546.61 / 30 = 18.2 m/sec
Cyclist x travels 600 m / 30 = 20 m/sec average speed assuming 20 sec over each 200 m interval (total displacement of X = 600 m)
Cyclist Y travels 546.61 m / 30 = 18.2 m/s average speed
