How does a supernova occur?

Answers

Answer 1
Answer: Supernova occurswhen black holes stretch so much running out of nuclear fuel. When a starcollapses to form a black hole, its mass increases. Supernovas have greatermasses than black holes. One example application of this is the theory of BigBang. Fromtheories such as Ekpyrotic theory, White Holes, Matrix theory, and Quantumtheory, the Big Bang theory is the theory mostly accepted by scientists.According to the theory, the universe started as a singularity, that is, from ablack hole under extreme gravitational pressure and expanded (instead ofexploded) and cooled. Its cooling, according to the theory, is still happeningnow as of the moment.

The mass of a lamb that weighs 110 n is about a. 1 kg.
b. 11 kg.
c. 110 kg.
d. 1100 kg.
e. none of the above

Answers

A lamb that weighs 110 N has a mass of around 11 kg. Hence, option B is correct except B all options are incorrect.

What are Mass and Weight?

The mass of a physical body is a measure of its entire makeup. Inertia, or the body's resistance to acceleration when a net force is applied, is also measured by this term. The strength of a body's gravitational pull on other bodies is also influenced by its mass. The kilogram is the fundamental mass unit of the SI.

In physics and engineering, the weight of an object refers to the gravitational force that pulls on it. Weight is the term used in many widely used textbooks to describe the gravitational force acting on the object. Some people think of weight as a scalar quantity that gauges the gravitational force's strength.

According to the question, the given values are :

Weight, w = 110 N and,

Taking value of g = 10 m/s²

As we know that  :

w = m × g

110 = m (10)

m = 11 kg

Hence, the mass of the lamb will be 11 kg.

g = 10 m/s²
w = 110 N

w = m x g
110 = m x 10
110 = 10 m
m = 110/10 = 11 kg

The diagram shows the path of a pendulum bob that has been released.Which describes the kinetic energy of the pendulum bob?



A.
It increases as it travels from its maximum amplitude to its resting point.

B.
It decreases as it travels from its maximum amplitude to its resting point.

C.
It remains the same throughout the period.

D.
It decreases at the arm, but increases at the pivot point

Answers

The right answer for the question that is being asked and shown above is that: "B. It decreases as it travels from its maximum amplitude to its resting point." the statement that describes the kinetic energy of the pendulum bob is that It decreases as it travels from its maximum amplitude to its resting point.

a car traveling at 40m/s starts to decelerate steadily. it comes to a complete stop in 12 seconds. what is the acceleration?

Answers

Velocity - v =0 m/s,

initial velocity - v(0)= 40 m/s

a - acceleration,

time - t = 12 s.

v=v(0) - at

0 = 40m/s - a*12s

12a = 40

a = 3.3 m/s²


What do we mean by the main-sequence turnoff point of a star cluster, and what does it tell us? It is the spectral type of the hottest main sequence star in a star cluster, and it tells us the cluster's age. It is the point in a star cluster beyond which main sequence stars are not found, and it tells us the cluster's distance. It is the faintest and coldest main sequence star in a cluster, and it tells us the cluster's age. It is the mass of the most massive star in the star cluster, and it tells us the cluster's size.

Answers

Answer:

Explanation: The turnoff point for a star refers to the point on the Hertzsprung–Russell diagram where it leaves the main sequence after its main fuel is exhausted-the main sequence turnoff. HR diagrams for two open clusters, M67 and NGC 188, showing the main sequence turn-off at different ages.
