Answer:
Explanation:
Experts in this field report that the modulation is FM or frequency modulation. There are exceptions, but they were not listed.
The usual frequencies allocated to these toys is 27 MHz and 72 Mhz.
There is not much chance of interference because the range is small even with a good transmitter.
Answer: 11.1cm
Explanation:
Object distance (u) = 32cm
Image distance(v) = 17cm
Focal length(f) =?
Lens formular:
1/f = 1/u + 1/v
1/f = 1/32 + 1/17
Taking the L. C. M of 17 and 32
1/f = (17 + 32) / 544
1/f = 49/544
Taking the reciprocal
f = 544/49
f = 11.1 cm
Therefore, Focal length of the lens is 11.1cm
Answer: 20.4 miles
Explanation:
Here we need to use the equation:
Velocity = Distance/Time.
Initially we have that he can travel 30 miles in 2 hours, so the velocity is:
V = 30mi/2h = 15mph
Now, we reduce the velocity by 3 mph, so the new velocity is 15mph - 3 mph = 12mph.
Now we want to know the distance traveled in 1.7 hours with this velocity, this is.
Velocity*Time = Distance
12mi/h*1.7h = 20.4 miles
The answer is b. Negative terminal.
The AMA is calculated as:
AMA = force obtained / force applied
AMA = 400 / 40
AMA = 10
