The planet would stay in the same orbit but start revolving faster.
(Its year would get shorter.)
Answer:
dv = 1.03 inch^3
Explanation:
given data:
diameter = 3 inch
radius = 1.5 inch
height 4 inch
top and bottom thickness is 0.02 inch
side thickness = 0.015 inch
we know that volume of the cylinder is given as
by definition of differential we have
where dh = -(0.02 + 0.02) = 0.04 inch [ sum of top and bottom thickness]
the radius is decreased by 0.02 inch, dr = 0.02 inc,
dv = 37.69*(0.02) + 7.06*(0.04)
dv = 1.03 inch^3
Answer:
The key point was that Kennedy challenged Nixon to a series of televised debates. It was the first televised presidential debate in American history.
In 1960, 88 % of American homes had television. About 2/3 of the electorate watched the first debate on TV. Nixon was recovering from a knee injury, he looked drained. Kennedy, meanwhile, had been resting in a hotel for an entire weekend, he looked tan and confident.
Most Americans watching the debates voted for Kennedy, most radio listeners seemed to give the edge to Nixon. hope this helps
Noise could be defined as electromagnetic fields that affect analog signals that are constantly changing. This process does not occur in a similar way with digital signals, which have fixed electrostatic pulses (For this reason they are able to withstand 'noise' because the power of these signals are much stronger than the power coming from noise).
That phenomenon does not happen with the analog signals which have a variable intensity and become vulnerable to any electronic noise interference.
When very high electromagnetic fields are generated, the waves of the analog signal cannot be perceived which causes problems in the transmitted signal (making it unintelligible to the receiver)
Answer:
(a) Velocity of target is 2.7 m/s.
(b) Mass of target is 0.807 kg.
Explanation:
Mass of ball 
initial speed of the ball 
Final speed of the ball 
Part (a) The second ball is initially at rest. So, by the conservation of momentum,
Now, the velocity of approach is equal to the velocity of separation,
Part (b): From equation (1),
