Answer:
C) 160 N
Explanation:
= mass of the car = 2000 kg
Weight of the car is given as

= Force exerted on the input piston
= Area of input piston = 10 cm x 10 cm = 0.1 m x 0.1 m = 0.01 m²
= Area of lift = 1 m x 1.2 m = 1.2 m²
Using Pascal's law

Answer:
its a shield that can protect us from super hot rays and all though ita not that strong atleast we wont get burned to death lol :)
20 is the atomic number for Calcium.
Answer: Angle 59 degree
Explanation: Given that the
n1 = 1.0
n2 = 1.5
Øi = 35 degree
From Snell law, which says that
n1/n2 = sinØ1/ sinØ2
Substitute all the parameters into the formula
1/1.5 = sin 35/sinØ2
Cross multiply
Sin Ø2 = 1.5 sin35
SinØ2 = 1.5 × 0.573 = 0.860
Ø2 = sin^-1(0.860)
Ø2 = 59.36 degree
Ø2 = 59 degree ( approximately)
It has angle 59 degree when passing from air to glass
