Answer:
O Distance
Explanation:
With the given information, it is possible to find the distance of the car has traveled on the home from school.
This is possible because distance is the length of path a body covers.
From the given values:
Distance = 5208 - 5200 = 8miles
It is not possible to find the displacement because no direction was given.
Also velocity is not possible since the time frame of travel was not state.

Answer:
T_ac = 6.586 KN
R = 10.51 KN
Explanation:
Given:
- Tension in cable T_ab = 9.1 KN
Find:
- Determine the required tension T in cable AC such that the net effect of the two cables is a downward force at point A
- Determine the magnitude R of this downward force.
Solution:
- Compute the three angles as shown in figure attached, a, B , y:
a = arctan (40/50) = 38.36 degrees
B = arctan (50/30) = 59.04 degrees
y = 180 - 38.36 = 82.6 degrees
- Use cosine rule to calculate R and F_ac as follows:
sin(a) / T_ac = sin(B) / T_ab = sin(y) / R
sin(38.36) / T_ac = sin(59.04) / 9.1 = sin(82.06) / R
T_ac = 9.1 * ( sin(38.36) / sin(59.04) )
T_ac = 6.586 KN
R = 9.1 * ( sin(82.06) / sin(59.04) )
R = 10.51 KN
<h2>
Answer: C. 7.67 W </h2>
Explanation:
Firstly, we are told the three resistors are <u>connected in parallel</u>, this means we have to use the following equation to find the total resistance of the circuit:
(1)
Where: , ,
Solving (1):
(2)
(3)
(4) This is the total resistance of the circuit
On the other hand, the total power of this circuit is given by the following equation:
(5)
Where is the total voltage of the circuit.
Solving:
(6)
Finally:
(7) This is the total power of the circuit in Watts (W)
A lower, easier gear, with the smaller chain ring up front and a largercog in the back, lets you accelerate faster.
