okay u need to use the equation m=Fnet/a. Fnet=540N a=7.74m/s^2 m=540N/7.74m/s^2=69.77kg
Answer:
both experience forces or at least a force
Explanation:
it would go in the direction the other object
(second object, the one that crashed) was going
si if going right then right if left then left

Answer:
A
Explanation:
Kinetic energy is the energy of an object that is moving, so D is immediately out as it is potential energy. A baseball flying at 90 mph has the greatest amount of kinetic energy because it has a higher speed.
Answer: The train traveled 210 miles in 6 seconds of time duration.
Explanation:
The initial velocity of the train,u = 50 mile/s
Acceleration of the train ,a =
Duration of time ,t = 6 seconds
Using second equation of motion :
The train traveled 210 miles in 6 seconds of time duration.
The correct answer of this question is : Artificial luminous sources.
EXPLANATION :
As per the question, we are given some light sources like halogen, laser, sodium-vapor etc.
There are two types of bodies which are known as luminous and non luminous depending on their production of light.
All these sources given in the question are luminous sources as they have their own light. Most importantly they are not natural luminous sources like stars, firefly etc.
All these sources are artificial.
Hence, the correct answer of this question is artificial luminous sources.
