As we know that gravitational force on two planets will be given as
let
mass of star = M
mass of two planets are m1 and m2
their distance from star is r1 and r2
since the gravitational force of star is given on two planets to be same
so here we can say
now if the ratio of mass and distance is same then we can say that closer planet must have lesser mass to hold good for above equation
so correct answer will be
B) Yes, it is possible if the closer planet has less mass.
Mass and Volume would be the answer
Answer:
Explanation:
Frictional force = 7000 N
mass of car = 1300 kg . Initially car was moving uniformly so no force acting on car at that time . After frictional force acts , it creates deceleration or negative acceleration .
acceleration = force / mass
= - 7000 / 1300
= - 5.38 m / s²
Answer:
a=2.304×10¹⁶m/s²
Explanation:
Given data
Distance d=2.5 nm=2,5×10⁻⁹m
Mass of proton m=1.6×10⁻²⁷kg
charge of proton q=1.6×10⁻¹⁹C
To find
acceleration a
Solution
Apply the Coulombs Law
Where k is coulombs constant (k=9×10⁹Nm²/C²)
q=q₁=q₂
r=d
So
Answer:
1. The five phases of matter. There are four natural states of matter: Solids, liquids, gases and plasma. The fifth state is the man-made Bose-Einstein condensates. In a solid, particles are packed tightly together so they don't move much.
2. The temperature at which a substance changes from the liq- uid state to the solid state is called the freezing point. The freez- ing point of the liquid state of a substance is the same temperature as the melting point of the solid state. For example, solid water melts at 0°C and liquid water freezes at 0°C.
3. The process of a liquid becoming a gas is called boiling (or vapourization), while the process of a gas becoming a liquid is called condensation. 4. Sublimation is the process of transformation directly from the solid phase to the gaseous phase, without passing through an intermediate liquid phase.
