Given R2’s resistance and voltage we can find the current through it of 1.5 amps. Due to Kirchhoff’s junction rule the current going in must match the current going out so the current through them all is 1.5 amps. Using this we can find the voltage through R1 of 15v. Then we subtract V1+V2 from 120 to find that R3 has a voltage of 60v. Next we find that R3 has a resistance of 40 ohms
Answer:
k = 9.6 x 10^5 N/m or 9.6 kN/m
Explanation:
First, we need to use the expression to calculate the spring constant which is:
w² = k/m
Solving for k:
k = w²*m
To get the angular velocity:
w = 2πf
The problem is giving the linear velocity of the car which is 5.7 m/s. With this we can calculate the frequency of the car:
f = V/x
f = 5.7 / 4.9 = 1.16 Hz
Now the angular velocity:
w = 2π*1.16
w = 7.29 rad/s
Finally, solving for k:
k = (7.29)² * 1800
k = 95,659.38 N/m
In two significant figures it'll ve 9.6 kN/m
Answer:
The tea will generally stop cooling when it reaches room temperature ️
The temperature of the body is equal to 39.48°C
Why?
To find the temperature of the body that produces 9.0cm of this mercury column, we need to use the formula for linear interpolation. Also, the temperatures to use are based on the Celsius degrees scale.
For the fixed tempetatures, we have:
We need to use the following formula for linear interpolation:
Then, we have:
So, interpolating we have:
Hence, the temperature of the body is equal to 39.48°C
Have a nice day!
The motion diagram for A-E is attached.
F) The drawings will change to reflect how the spacings of the respective positions are changing more irregularly.
<h3>What are motion diagrams?</h3>
A motion diagram is an image that represents the position of an object at various relatively spaced time intervals.
The art of using motion diagrams is called kinematics. it is useful for detecting the unknown speed of objects. For example, the movement of a rocket from earth to space, the movement of a ship over the water.
