Answer:
Focal length of the mirror will be 660 mm
Explanation:
We have given that sunlight is focused at a distance of 330 mm in front of mirror
So focal length f = 330 m
We have to find the radius of curvature
Radius of curvature is double the focal length
So radius of curvature = 2× focal length = 2×330 = 660 mm
So focal length of the mirror will be equal to 660 mm

Answer:
A signal is produced.
Radio waves are modulated and amplified.
Radio waves are amplified and demodulated.
A signal is seen, heard, or used.
Explanation:
Communication is the method of transmitting information between two or more participants. A radio communication network is a set of static and wireless radio equipment developed to facilitate an entity by enabling particular modes of communication such as one-to-many and one-to-one communication. Radio waves are being used to transmit information spatially from the sender to receiver, by modulating the radio signal in the transmitter. The above steps explains the loop of the radio communication system.
M = 10kg
P = 40 kg.m/s
V= 4m/s
Formula v = p/m
V= p/m
=4okg.m/s / 10kg
=4m/s
Answer:
Liquid has a defined volume but undefined shape
Explanation:
Explanation:
Solid has specific shape and volume
Liquid has specific volume but no specific shape
Gases have no specific volume and no specific shape
So correct answer is liquid.
