According to the third rule of series circuit, the total voltage is equal to the sum of individual voltages. These proves that the statement above "<span>When voltage sources are connected in series, the total voltage is equal to the algebraic sum of the individual voltages?" is TRUE.</span>
Answer: 53.06
Explanation: Center of mass is an average of masses factored by their distance from a reference point. To determine the center of mass, it can be used the following formula: x =
For this question: The system is of two people and the reference is (0,0)
The center of mass for the x-coordinate is:
Note the terms 'i' and 'j' represents x-coordinate and y-coordinate, respectively
x =
x =
x =
x = 53.06
The x-coordinate of the <u>center of mass</u> is <u>53.06</u>.
The length of the string must vary, while the angle and acceleration are constant
Answer:
Time = 13 seconds
Explanation:
Given the following data;
Speed = 5m/s
Distance = 65m
To find the time;
Speed = distance/time
Time = distance/speed
Time = 65/5
Time = 13 seconds
Therefore, it will take the stone 13 seconds to hit the ground below.
Answer:
Explanation:
Magnitude of frictional force = μ mg
μ is either static or kinetic friction.
To start the crate moving , static friction is calculated .
a ) To start crate moving , force required = μ mg where μ is coefficient of static friction .
force required =.517 x 56.6 x 9.8 = 286.76 N .
b ) to slide the crate across the dock at a constant speed , force required
= μ mg where μ is coefficient of kinetic friction , where μ is kinetic friction
= .26 x 56.6 x 9.8 = 144.21 N .
