Answer:
The answer is below
Explanation:
1.5 - kΩ resistor is connected to an AC voltage source with an rms voltage of 120 V. (a) What is the maximum voltage across the resistor? (b) What is the maximum current through the resistor? (c) What is the rms current through the resistor? d) What is the average power dissipated by the resistor?
Solution:
The rms value of current and voltage shows the alternating quantity of the voltage and current.
Given that V(rms) = 120 V, R = 1.5 kΩ
a) The maximum voltage across the resistor is given as:
b) The maximum current through the resistor is:
c) The rms current through the resistor is:
d) The average power dissipated by the resistor is:
V=D/T
V=107 m / 27 s - divide distance by time
V= 4 m/s - because when we round 3.9629 in the nearest 10th we will get 4.

Answer:
The rolling basketball has greater momentum.
Explanation:
The momentum of an object is defined as the product of mass and velocity.
Given that the bowling mass has a greater mass than the basketball,
The bowling ball is at rest, so the velocity if the ball is zero.
The basketball is rolling, it has some velocity associated with it.
Therefore, the momentum of the bowling ball is zero.
The basketball has some momentum associated with it.
Hence, the rolling basketball has greater momentum.
Answer:
c(t)= 40t
Explanation:
As it forms the right angle triangle. see attachment for the figure.
We will use Pythagoras theorem i.e
a² + b² = c²
where,
'a' is perpendicular
'b' is base
'c' is hypotenuse i.e the distance D between the ships in terms of the time 't'
the distance 'a' from the starting point is 24t
the distance 'b' from the starting point is 32t
therefore,
(24t)²+ (32t)² = c(t)²
c(t)= √(24t)²+ (32t)²
c(t)= √576t² + 1024t²
c(t)=√ 1600t²
c(t)= 40t
Thus, function that models the distance D between the ships in terms of the time t (in hours) elapsed since their departure is 40t

a) Dalton
Explanation:
In <u>Dalton's</u> model atoms are imagined as tiny balls. This model was introduced in the year 1803 by John Dalton.
