Explanation:
Newton’s Second Law of Motion
Newton’s Second Law of Motion states that ‘when an object is acted on by an outside force, the mass of the object equals the strength of the force times the resulting acceleration’.
This can be demonstrated dropping a rock or and tissue at the same time from a ladder. They fall at an equal rate—their acceleration is constant due to the force of gravity acting on them.
The rock's impact will be a much greater force when it hits the ground, because of its greater mass. If you drop the two objects into a dish of water, you can see how different the force of impact for each object was, based on the splash made in the water by each one.
Geometrically, a screw can be viewed as a narrow inclined plane wrapped around a cylinder. Like the other simple machines a screw can amplify force; a small rotational force (torque) on the shaft can exert a large axial force on a load.
Answer:24888.8g
Explanation: 28cupcakes calls 360g
32 cupcakes calls ???
28x32=896 cupcakes
896/360= 2.4888888g
In four decimal place = 24888.8grams
Answer:
39.11 Hz
Explanation:
Data provided in the question:
Frequency of sound emission, = 37.5 kHz = 37500 Hz
Speed of bat, = 0.021 times the speed of sound
Now,
Frequency heard by bat =
Therefore,
The Frequency heard by bat will be =
or
Frequency heard by bat will be=
or
Frequency heard by bat will be = 39108.78 Hz = 39.11 Hz
