Answer:
Explanation:
Given
Velocity of bat
Frequency of sound
velocity of sound
using Doppler Effect apparent frequency is given by
where
apparent frequency
v=velocity of sound in the given media
velocity of source
velocity of observer
here velocity of source is zero
as source is travelling towards source thus
Answer:
<h3>The answer is 300 N</h3>
Explanation:
The force acting on an object given the mass and acceleration we use the formula
<h3>force = mass × acceleration</h3>
We have
force = 15 × 20
We have the final answer as
<h3>300 N</h3>
Hope this helps you
The most effective forces on the object are the backward force of air resistance relatively very small in magnitude, and the force of gravity. Because the spiral path of the satellite is not perpendicular to the gravitational force, one element of the gravitational force pulls forward. at the satellite to do fantastic work & make its speed increase.
<h3>What is called gravitational force?</h3>
Gravity, additionally referred to as gravitation, is a force that exists amongst all material gadgets withinside the universe. For any objects or particles having nonzero mass, the force of gravity tends to draw them in the direction of each other. Gravity operates on objects of all sizes, from subatomic particles to clusters of galaxies.

Answer:
Elbow Lake
Explanation:
An oxbow lake is a stagnant lake that forms along a winding river due to soil erosion resulting in an abandoned stream, cut off from the river. An oxbow lake begins as meander or a curve in a river after some time, the curve becomes larger as a result of erosion and hydraulic action.
