Answer:
Mechanical waves are waves that need a medium for propagation. Non-mechanical waves are waves that do not need a medium for propagation.

I hope its helped thank you !! ( don't report my asnwer just delete it ) brainlest pls if u can
Answer:
The amount of power will be increased.
Explanation:
If the work remains constant but the time is reduced the power increases. Since power is defined as the relationship between work overtime. By means of the following equation, we can see this relationship.
where:
P = power [Watts]
W = work [J] (units of joules)
t = time [s]
Let's assume with an example the above written.
If we have an electric motor that exerts a work of 950 [J], and the time used is 5 [s], the power is:
![P = 950/5\\P = 190 [W]](https://tex.z-dn.net/?f=P%20%3D%20950%2F5%5C%5CP%20%3D%20190%20%5BW%5D)
Now if we want to accelerate the work done and use 2 seconds for the time, we will have:
![P=950/2\\P=475 [W]](https://tex.z-dn.net/?f=P%3D950%2F2%5C%5CP%3D475%20%5BW%5D)
Answer:
i found this on google "A universal gate is a gate which can implement any Boolean function without need to use any other gate type. The NAND and NOR gates are universal gates. In practice, this is advantageous since NAND and NOR gates are economical and easier to fabricate and are the basic gates used in all IC digital logic families.

Answer:
<h3>0.77m/s</h3>
Explanation:
According to law of conservation of energy
m1u1 + m2 u2 = (m1+m2)v
m1 and m2 are the masses of the bodies
u1 and u2 are the initial velocities
v is the final velocity after collision
Substitute the given values into the formula
1055(0) + 660(2) = (1055+660)v
0+1320 = 1715v
v = 1320/1715
v = 0.77m/s
Hence the final velocity of each vehicle is 0.77m/s
Power = (voltage) x (current)
Divide each side by 'voltage': Current = power / voltage
= (60 watts) / (120 volts) = 0.5 ampere
