The mass of the rider 1 is 4 g.
<h3>
The use of a rider in mass measurement</h3>
Rider is a metallic wire piece which is of certain mass and can be bent . It can move the beam of the Paul Bunge Balance.
The riders are the sliding pointers positioned on top of the beams to show the pan and beam weight in grams.
<h3>Mass of the rider 1</h3>
The mass of the rider 1 is obtained by subtracting mass of riders as show below.
mass of rider 1 = mass of object - (mass of rider 2 + mass of rider 3)
mass of rider 1 = 694 g - (600 g + 90 g)
mass of rider 1 = 694 g - 690 g
mass of rider 1 = 4 g
Thus, the mass of the rider 1 is 4 g.

Answer:
P = 517.5 [kg*m/s]
Explanation:
We must remember that momentum is defined as the product of force by the time of force duration.
where:
P = momentum [kg*m/s]
F = force [N]
t = time [s]
![P=345*1.5\\P=517.5[kg*m/s]](https://tex.z-dn.net/?f=P%3D345%2A1.5%5C%5CP%3D517.5%5Bkg%2Am%2Fs%5D)
Answer:
<u>Translated from Polish language:</u>
- Coil connected in series ul = 120 resistor ur = 100 and capacitor uc = 50 Voltage with voltmeter must not be:
- The voltmeter must not be connected in series rather it should be connected in parallel to the circuit to provide much effective results for analyzing the circuits potential difference.
Answer:
A mousetrap makes use of a simple machine called a lever.
Explanation:
In a second-class lever the effort force is at the other end, with the load in the middle. In a third-class lever, the load is at the end and the effort force is between the fulcrum and the load. When you set the mousetrap, you are using a second-class lever. Sorry if I get this wrong. I am in 5th grade! ♥
