<span>The protons and neutrons are much more massive than the electrons.
</span>
The electrons are simply too small to really change the mass, so they aren't counted.
Answer:
4m/s
Explanation:
due to newtons second law of motion
the accelerations that result when a 12-N net force is applied to a 3-kg object. A 3-kg object experiences an acceleration of 4 m/s/s.
HOPE THIS HELPS PLEASE MARK AS BRAINLIEST:)
Answer:
for question 5 its
Explanation:
Through Brahe's astronomical measurements and Kepler's own drawings of the geometrical relationship between the Sun and Mars in various parts of the planet's orbit, Kepler discovered that planets moved faster when they were closer to the Sun.
initial speed of the racer is given as
after applied force the final speed is given as
now during this speed change the racer will cover total distance 185 m
so here we will use kinematics
now the force that chute will exert on the racer will be given as
B) here following is the strategy for solving it
1. first we used kinematics to find the acceleration of the car
2. then we used Newton's II law (F = ma) to find the force
Answer:
D. a person pulling a sled.
Explanation:
contact force only occurs when something directly comes in contact with another object.
a. is wrong because that is called magnetic force.
b. gravitational force
c. is an electrical force
