The statement "force equals mass times acceleration (F = ma)" is Newton's second law of motion. Why is this a law rather than a theory?Options:
a) It has been extensively tested and confirmed through experimentation.
b) It is a hypothesis that is yet to be proven.
c) It is a general explanation for a wide range of phenomena.
d) It is based on mathematical equations but lacks empirical evidence.

Answers

Answer 1

Answer:

Answer:

What if a wave reaches a type of matter it cannot pass through? Does
it just stop moving? If not, where does
it go?

Answers

It is bounced back. Like echoing, it's basically the sound wave hitting the matter it can't go through and bounce back.

if it hit the matter that it cannot pass through.....according to the velocity of wave..it might get reflected back....we can find sound waves reflecting back in closed rooms...because of the presence of the matter through which it cannot pass....and...it's because of this tht...echo is observed

image distance,di=10 cm

object distance,do=20cm

magnification, m=di/do

=10/20

=0.5

since the image is virtual, magnification is negative.

therefore m=-0.5

What is the law of inertia?

Answers

Inertia: Objects tend to move at the same speed and direction or, if at rest, stay at rest. A force has to be applied to overcome inertia. An objects inertia is determined by the mass of the object.

Answer:

The law of inertia is mostly known the same as THE NEWTONS FIRST LAW OF MOTION which states that"A body will continue to its state of rest or motion unless acted by an external forces"

●WHAT IS INERTIA?

Inertia is the ability of a body at rest to resist motion or a body in motion to resist resting unless acted by external forces.

△TYPES OF INERTIA

■There are 3 types of inertia,

◎Inertia of rest

◎Inertia of direction

◎Inertia of motion

White light is shining on a green grape. The grape _____.absorbs green light

Scientists have found ancient rock formations dating to the late Proterozoic eon in South America. These ancient rocks can be found from the eastern edge of South America's continental shelf, which extends just off the coast of Brazil, to the interior of the continent. This general location is indicated by a green circle on the map below. Scientists have also found rock formations made out of the same type of rock and from the very same eon at another location. The location of this second group of rock formations strongly supports the current theory of plate tectonics.
