Answer:
The smallest possible beat frequency when B and C are sounded together is 3 Hz
Explanation:
Given;
the beat frequency of A and B = 2 Hz
the beat frequency of A and C = 5 Hz
Beat frequency is equal to the difference in frequency of the two notes that interfere to produce the beats.
Therefore, the smallest possible beat frequency when B and C are sounded together is 3 Hz
Answer:
Change in x direction is
Change in y direction is
Explanation:
The temperature is given by we need to find gradient of temperature to obtain the rate of change thus
Now the rate of change at (3,1) in
1) X direction is given by
2) Y direction is given by
Answer:
(a). The speed at the moment of being thrown is 30.41 m/s.
(b). The maximum height is 47.18 m.
Explanation:
Given that,
Weight of stone = 3.00 N
Height = 15 m
Speed = 25.0 m/s
(a). We need to calculate the speed at the moment of being thrown
Using work energy theorem
Put the value into the formula
(b). We need to calculate the maximum height
Using work energy theorem
Here, =0
Put the value into the formula
Hence, (a). The speed at the moment of being thrown is 30.41 m/s.
(b). The maximum height is 47.18 m.
