Answer:
the phone call goes out, transmits through radio waves, then moves to the central hub. then the signals go to the nearest tower to the receiver if the call
Use pythagorean's theorem for this, with 7 as a and 5 as b. pythagorean's theorem says that a^2 + b^2 = c^2, so 7^2 * 5^2 = c^2. this gives you 49 + 25 = c^2, so 74 = c^2. c = sqrt 74, which is approximately 8.60 km
The Correct choice is ~
D. 18.0 Newtons
because the resultant force can't exceed 16 Newtons ~
Answer:
1. The momenta of the skaters after the shove are equal in magnitude but opposite in direction. Skater Z's mation is an ex. of recoil.
Explanation:
The moment is preserved before and after the push (impact), this is called conservation of the moment, skater x will move in the direction of the force of the push, but skater z will move in the opposite direction with a different speed, but retaining the initial moment imparted.
Recall that linear momentum is defined as the product of body mass by Velocity
P = m * v
where:
P = linear momentum [kg*m/s]
m = mass [kg]
v = velocity [m/s]
Answer:
Analog,Noise,Digital,less
Explanation:
Analog signal changes continuously with time and moves smoothly.
Due to this analog signal can easily disturbed by noise.
Since digital signal are like square wave due to this digital signals are less affected by noise.
Because the Analog signal changes smoothly, like a sine wave, it can closely mimic a human voice. However, part of the signal can easily get lost to Noise. Because Digital signals are on or off, like a square wave, they best carry information that can easily be converted into numbers. These signals are less affected by noise.
