The features of an object which affect its weight are the mass and location which is denoted as option A.

This is defined as the force acting on the object due to gravity and the formula is W = mg where m is mass and g is acceleration due to gravity.

This is why the weight features of an object is affected by its mass and then location.

Answer:

3.4 s

Explanation:

Given:

Δy = 0 m

v₀ = 17 m/s

a = -10 m/s²

Find: t

Δy = v₀ t + ½ at²

0 m = (17 m/s) t + ½ (-10 m/s²) t²

0 = 17 m/s − (5 m/s²) t

The type of galaxy which has arms that contain sites of active star formation and start close to a bulge in the center is: D. normal spiral.

A star can be defined as a giant celestial (astronomical) object that is made up of a luminous sphere of plasma bounded together by its own gravitational force.

Generally, a star comprises two (2) main interstellar hot gases and these include:  

I. Hydrogen (H).

II. Helium (He).

A galaxy refers to a collection of billions of stars, which are existing independently.

This ultimately implies that, the greatest number of stars are found in a galaxy.

According to astronomers, the galaxy is classified into four (4) main categories and these are:

Furthermore, spiral galaxies are divided into two (2) major groups such as:

I. Barred spiral.

II. Normal spiral.

A normal spiral is typically made up of arms containing sites of active star formation and it start close to a bulge in the center.

[tex] \boxed{\sf Distance \ travelled = 62.5 \ m} [/tex]

Given:

Initial velocity (u) = 25 m/s

Final velocity (v) = 0 m/s (Rest)

Time taken (t) = 5 seconds

To Find:

Distance travelled by car (s)

Explanation:

From equation of motion of object moving with uniform acceleration in straight line we have:

[tex] \boxed{ \bold{s = (\frac{v + u}{2} )t}}[/tex]

By substituting value of v, u & t in the equation we get:

[tex] \sf \implies s = ( \frac{0 + 25}{2} ) \times 5 \\ \\ \sf \implies s = \frac{25}{2} \times 5 \\ \\ \sf \implies s = 12.5 \times 5 \\ \\ \sf \implies s = 62.5 \: m[/tex]

[tex] \therefore[/tex]

Distance travelled by car (s) = 62.5 m

The distance  car travel during that time is 62.5 meter.

Acceleration is the rate at which speed and direction of velocity vary over time. A point or object going straight ahead is accelerated when it accelerates or decelerates.

Even if the speed is constant, motion on a circle accelerates because the direction is always shifting. Both effects contribute to the acceleration for all other motions.

Initial velocity (u) = 25 m/s

As the car becomes rest, final velocity (v) = 0 m/s (Rest)

Time taken (t) = 5 seconds.

The deceleration of the car: a = (initial speed - final speed)/time interval

= ( 25 m/s - 0 m/s)/5 second

= 5 m/s²

The distance  car travel during that time = ut - at²/2

= 25 × 5.0 meter - (5×5²/2) meter

= 62.5 meter.

Hence, the distance  car travel during that time is  62.5 meter.

Answer:

F= 5000 N

Explanation:

This problem is related to force on a body, and to tackle it we need to apply newtons first law of motion which states that "a body will continue to be at rest or uniform motion except acted upon by an external force greater than the force keeping the body at rest or uniform motion"

given

mass m= 200kg

acceleration a= 25 m/s

we know that

F= ma

F= 200*25

F= 5000 N

A hurricane is just like any other low-pressure system.  

But it gets bigger, and stronger, and picks up a lot of rain, by passing over warm, tropical ocean water.

If anything like climate change or hot fish were to come along and make that water warmer, then there would be more energy for the low pressure system to absorb from the warmer water.  Then it would get even bigger and stronger, and it would pick up even more rain on its way over.

Also, normal-size low-pressure systems over the ocean that could never become tropical storms or hurricanes before, COULD do it now that the ocean is warmer.  (Notice how this year, 2020, there have been so many hurricanes and tropical storms that NOAA ran out of names for them, and had to start using Greek letters.  This has only happened once before.)

To Find:

Acceleration (a) of the car

Explanation:

From equation of motion we have:

By substituting value of v, u & t in the equation we get:

Answer:

1. 0.2 g/cm³.

2. 1 g/cm³.

3. 0.72 g.

Explanation:

1. Determination of the density of the bread.

Volume (V) = 2270 cm³

Mass (m) = 454 g

Density (D) =?

The density of a substance is simply defined as the mass of the substance per unit volume of the substance. It is represented mathematically as:

Density (D) = mass (m) /volume (V)

D = m/V

With the above formula, we can calculate the density of the bread as follow:

Volume (V) = 2270 cm³

Mass (m) = 454 g

Density (D) =?

D = m/V

D = 454/2270

D = 0.2 g/cm³

Therefore, the density of the bread is 0.2 g/cm³.

2. Determination of the density of water.

Volume (V) = 1 L

Mass (m) = 1000 g

Density (D) =?

Next, we shall convert 1 L to cm³. This can be obtained as shown below:

1 L = 1000 mL

1 mL = 1 cm³

1000 mL = 1000 cm³

Therefore,

1 L = 1000 mL = 1000 cm³

Therefore, 1 L is equivalent to 1000 cm³.

Finally, we shall determine the density of water as follow:

Volume (V) = 1000 cm³

Mass (m) = 1000 g

Density (D) =?

D = m/V

D = 1000 / 1000

D = 1 g/cm³

Therefore, the density of water is 1 g/cm³.

3. Determination of the mass of the block of wood.

Density (D) = 0.6 g/cm³

Volume (V) = 1.2 cm³

Mass (m) =...?

D = m/V

0.6 = m/1.2

Cross multiply

m = 0.6 × 1.2

m = 0.72 g

Therefore, the mass of the block of wood is 0.72 g.

Answer:

(a) 25 m

(b) 75 m

Explanation:

Given that the jogger runs at a constant rate of 10.0 m every 2.0 seconds.

So, the speed of the jogger,

[tex]v=\frac{10}{2}=5m/s\;\cdots(i)[/tex]

Let d be the distance covered by him in time, t s.

As distance=(speed) x (time)

So, [tex]d=vt[/tex]

From equation (i)

[tex]\Rightarrow d=5t\;\cdots(ii)[/tex]

As the jogger starts from origin, so, the distance, [tex]d[/tex], also represents the position of the jogger at the time [tex]t[/tex] s.

The position-time graph has been shown.

(a) From equation (ii), for t=5.0 s

[tex]d=5\times 5=25 m[/tex]

So, the jogger is at a distance of 25 m from the origin.

(b) Similarly, for t=15.0 s

[tex]d=5\times 15=75 m[/tex]

So, the jogger is at a distance of 75 m from the origin.

Answer:

The answer is

Explanation:

The kinetic energy of an object can be found by using the formula

[tex]KE = \frac{1}{2} m {v}^{2} [/tex]

where

m is the mass of the object

v is the speed or velocity

From the question

m = 1500 kg

v = 25 m/s

The kinetic energy of the object is

[tex]KE = \frac{1}{2} \times 1500 \times {25}^{2} \\ = 750 \times 625[/tex]

We have the final answer
