Answer:
its two valence electrons
Explanation:
Calcium is a group 2 element with two valence electrons. Therefore, it is very reactive and gives up electrons in chemical reactions.

Answer:
..
Explanation:
Coordinate adjectives are adjectives that describe the same noun equally. They should be separated with commas. In this sentence, both red and round are describing the ball. The correct answer is, "The red, round ball is Adley's favorite toy to play with."
The vehicle's centripetal acceleration is equal to 22.5m/s²
Radius, r = 10 meter
Speed, V = 15 m/s
To ascertain the car's centripetal acceleration
A(c) = V²/R
We obtain the following when we enter the formula's parameters:
A(c) = 152/10
A(c) = 225/10
A(c) = 22.5m/s²
<h3>What is Centripetal acceleration ?</h3>
When an item moves in a circular route, one of its motion characteristics is centripetal acceleration. Any motion in a circle with an acceleration vector pointing in the direction of the circle's centre is referred to as centripetal acceleration.
- Centripetal forces cause accelerations at the centripetal axis. With the exception of the Earth's rotation around the Sun, any satellite's circular motion around a celestial body is brought on by the centripetal force produced by their mutual gravitational pull.
Hence, Centripetal acceleration is
22.5 m/s²

From 50km/h to 0km/h in 0.5s we need next acceleration:
First we convert km/h in m/s:
50km/h = 50*1000/3600=13.8888 m/s
a = v/t = 13.88888/0.5 = 27.77777 m/s^2
Now we use Newton's law:
F=m*a
F=1700*27.7777 = 47222N
I am not sure if this is what your looking for but most machines use oil
