A boy of mass, m weights 895 N. What is his mass, m?

a) 895 kg
b) 8.95 kg
c) 89.5 kg
d) None of the above

Answer:

All magnets have north and south poles. Opposite poles are attracted to each other, while the same poles repel each other. When you rub a piece of iron along a magnet, the north-seeking poles of the atoms in the iron line up in the same direction. The force generated by the aligned atoms creates a magnetic field.

Answer:

Coal is fossil fuel extracted from earth and since it takes a long time to replenish, it is called a non renewable source of energy

Explanation:

Coal is formed from the fossil fuel that lie deep beneath the earth crust . These fossil fuels are dead remains of living organism that burried beneath the earth crust million of years ago.

Coal is non renewable because if once it gets depleted it will take a very very long time to replenish.

Answer: Coal is fossil fuel extracted from earth and since it takes a long time to replenish, it is called a non renewable source of energy

Two masses oscillating together with each of their time period as ,'T'

Option B

we know that,

The time period of a mass 'm' on a spring of spring constant 'k' can be strategize by the following equation :

[tex] \huge \rightarrow \: T \: = 2π \sqrt{ \frac{m}{k} } [/tex]

According to the question,

so,

The new time period would be

[tex] \huge \rightarrow \: T ' \: = 2π \sqrt{ \frac{2m}{2k} } [/tex]

[tex] \huge \rightarrow \: T ' \: = 2π \sqrt{ \frac{m}{k} } [/tex]

[tex] \huge \rightarrow \: T ' \: = T[/tex]

Hence ,option B is correct ✓

Answer:

Organic compounds are important because all living organisms contain carbon. They are the basic components of many of the cycles that drive the earth. For example, the carbon cycle that includes the exchange of carbon between plants and animals in photosynthesis and cellular respiration.

Answer:. The acceleration of the object is directly proportional to the force and inversely proportional to the mass.

Explanation:

According to Newton s Second Law of Motion, also known as the Law of Force and Acceleration, a force upon an object causes it to accelerate according to the formula net force = mass x acceleration.

Answer: The scientific revolution began in Europe toward the end of the Renaissance period, and continued through the late 18th century, influencing the intellectual social movement known as the Enlightenment

Explanation:

Answer:

Capacitance = 0.00058 Farads

Explanation:

Given the following data;

Charge, Q = 7mC to Coulombs = 7/1000 = 0.007C

Velocity = 12V

To find the capacitance;

Capacitance = charge/potential difference

Substituting into the equation, we have;

Capacitance = 0.007/12

Capacitance = 0.00058 Farads

Answer:

it's the star in the center of the star field

Explanation:

Why Doesn't Polaris Move? Polaris is very distant from Earth, and located in a position very near Earth's north celestial pole. ... Polaris is the star in the center of the star field; it shows essentially no movement. Earth's axis points almost directly to Polaris, so this star is observed to show the least movement

Answer: B

Explanation:

It will move slower than the light the object. The equation is Newton's 2nd Law of F = ma. If the force is constant, and the mass changes to something larger, then the acceleration must become smaller. You could also just do this yourself, push two objects with your hands. The heavier one will move slower assuming you used the same amount of force

Answer:

c

Explanation:

because newton's second law states that F= MA

which suggests that if M increases, F also increases which is the force,

let me give you a tip, during exam, just type any random numbers into the formula, like at first you type 5 into the M, then increase M, by putting 10 into the M , keep the acceleration the same for this, okay?

you will see that the force will increase,

by this I mean that option says largest mass, so the force will also be very big because in reality do you use more force on heavier box or a lighter one to push it across the room?

so larger mass, larger force, greater acceleration

but the question is not being clear, whether to the force remains constant for every object, if it does then A is false . and B is false because if the forces is constant, and it is light, it would require a small amount of force ,

but the other options, gave us a clue about the force so you can choose either c or d but see the explanation above,

the only corrext option will be c.

if not, please report this, someone will have a go at it

(Have a great day :D)

Answer:

Fales

Explanation:

That's why scientists and engineers often measure an object's mass—how much matter the object contains—rather than its weight. Mass stays the same regardless of location and gravity. You would have the same mass on Mars or Jupiter as you do here on Earth. Your weight is different on other planets due to gravity.

Answer:

A

Explanation:

A disadvantage is that sexual reproduction takes longer than asexual reproduction. A mate must be found, the egg must be fertilised by sperm, and then the offspring develop. ... This means that some individuals would survive and be able to reproduce and generate more offspring.

Answer:

force=mass × acceleration

8=2 × acceleration

acceleration= 8/2= 4 m/s²

Answer:4 m/s²
