Yellow and red dwarf stars are normal stars - they burn hydrogen in their cores and live on the main sequence of stellar lifetimes.
1. 6.0 m
force/mass× acceleration is the equation
since the accelaration is unknown you would divide 180 by the mass of 30kg which is 6
2.A
Answer:

Explanation:
Relative horizontal velocity of plane with respect to the car is given as

so we have


now we have



Now time taken by the object to drop the vertical height is given as



so the distance of the car must be



Angle of the car with horizontal is given as




An organism that eats another organism.
Predators hunt, and eat their prey.
Answer: 2000 J.
Explanation: Since work is force*displacement, we just have to multiply the force by the distance: w = f*d = 400 N*5.0 m = 2000 J.
