Answer:
microscopic light or Nano technology
Answer: Temperature inversion
Explanation: Temperature inversion is a reverse of the normal temperature flow or distribution of the air,it usually causes temperature to rise as altitude increase towards the troposphere instead of reduction of temperature.
Temperature inversion is caused when warm,dense air flow above cold,less dense air. Temperature inversion is hazardous to man as it traps pollutants close to the Earth surface,this condition limits vertical circulation.
Answer:
Explanation:
A car of mass 1000kg pushes 2000kg
The forward force is 4500N
Then, summation of the forward forces is ma
ΣF = Σ(ma) = m1a1 + m2a2
Since the body are moving together then, they will have the same acceleration(a)
ΣF = Σ(ma) = (m1+m2)a
Let m1=1000kg.
m2=2000kg
F=4500N
Then,
4500=(1000+2000)a
4500=3000a
Then,
a=4500/3000
a=1.5m/s²
They would float away!! And most likely go into orbit (plz mark Brainliest)
Linear momentum of an object is the product of the object’s mass and velocity. Linear momentum is a vector quantity, and the direction of momentum is taken to be the direction of the object’s velocity.
or an object with mass moving at a velocity , the angular momentum with respect to a reference point is defined using the cross product as:
where is the position vector of the object that describes the object’s position with respect to the reference point. The units for measuring angular momentum is kg m2 s-1. Since angular momentum is defined in terms of a cross product, the direction of the angular momentum vector is taken to be in a direction perpendicular to both the particle’s position vector and its velocity vector .
