Explanation:
hydrosphere, lithosphere, and biosphere interaction.
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:
a) Team A will win.
b) The losing team will accelerate towards the middle line with 0.01 m/
Explanation:
Given that Team-A pulls with a force , 
and Team-B pulls with a force , 
∵ 
The rope will move in the direction of force
.
∴ Team-A will win.
b) Considering both the teams as one system of total mass , 
Net force on the system ,
= 50-45 = 5N
Applying Newtons first law to the system ,
F = ma , where 'a' is the acceleration of the system.
Since , both the teams are connected by the same rope , their acceleration would be the same.
∴ 5 = 499×a
∴ a = 0.01 m/
Answer: Comets are basically floating chunks of ice, dust, and frozen gases. So, when comets are in space they cannot melt, So I'll say no :)
Answer - No, comets doesn't have a liquid center.
