A carrot has a mass of 69 grams and a volume of 150 cubic centimeters. Calculate its
density.

Answers

Answer 1

Answer:

As Per Provided Information

Mass of carrot 69 grams

Volume of carrot 150 cm³

we have been asked to determine the density of carrot .

Using Formulae

[tex] \bf \: Density = \cfrac{Mass \: of \: carrot}{Volume \: of \: carrot}[/tex]

Substituting the given value and let's solve it to determine the density of carrot.

[tex] \longrightarrow\sf \: Density = \cfrac{69}{150} \\ \\ \\ \longrightarrow\sf \: Density = \cancel\cfrac{69}{150} \\ \\ \\ \longrightarrow\sf \: Density =0.46 \: gm \: {cm}^{ - 3} [/tex]

Therefore,

Density of carrot is 0.46 gm/cm³

If the barge is made out of 4.8- cm -thick steel plate on each of its four sides and its bottom, what mass of coal can the barge carry in freshwater without sinking

Answers

The maximum mass of coal that the barge will carry in freshwater without sinking is 0.111 kg.

Volume of the barge

The volume of the barge is calculated as follows;

V = L³

V = (4.8 cm)³

V = 110.6 cm³

Density of the barge

For the barge to float in freshwater, its density must be less or equal to density of water.

density(barge) = density(water)

density(barge) = 1 g/cm³

Maximum mass to be carried by the barge without sinking

mass = density x volume

mass = 1 g/cm³ x 110.6 cm³

mass = 110.6 g

mass = 0.111 kg

Thus, the maximum mass of coal that the barge will carry in freshwater without sinking is 0.111 kg.

1. A hockey puck has a mass of 0.115-kg and strikes the pole of the net at (37 m/s)x. It bounces off in the opposite direction at (-25 m/s)x +(5 m/s)y. (A) What is the impulse on the puck? (B) If the collision takes .005s what is the force acted on the puck?

Answers

(a) The impulse on the puck is 1.323 kgm/s.

(b) The magnitude of the force that acted on the puck is 264.5 N.

Impulse of the puck

The impulse on the puck is equal to the change in momentum of the puck.

The change in th momentum of the puck is calculated as follows;

ΔP = m(u - v)

where;

v is the final velocity = (-25x + 5y) m/su is the initial velocity = 37 m/s

Magnitude of the final velocity

|v| = √[(-25)² + (5)²] = 25.5 m/s

ΔP = 0.115(37 - 25.5)

ΔP = 1.323 kgm/s

Thus, the impulse on the puck is 1.323 kgm/s.

Force on the puck

The magnitude of the force that acted on the puck is calculated as follows;

F = ΔP/t

F = 1.323/0.005

F =264.5 N

What is the difference between gravity and acceleration?

Answers

Aceleration refers to motion but gravity refers to force



Acceleration is change of velocity with time while gravity is the force of attraction pulling objects. When this force pulls an object it tends to move with a certain type of acceleration called acceleration due to gravity. This is equal to 9.8 m / s^2 for earth

Acceleration is the rate of change in velocity. While g is the acceleration due to gravity. The pace at which a body's velocity varies is represented by acceleration, which is a vector quantity.

What is acceleration?

The rate of change of velocity with respect to time is known as acceleration. According to Newton's second law, the eventual effect of all forces applied to a body is its acceleration.

[tex]\rm a = \frac{v-u}{t}[/tex]

u is the initial speed

v is the final speed

t is the time interval

a is the acceleration of the ball

Gravitation is a natural law by which all things with all matter are attracted towards one another.

g is the acceleration due to gravity. whose value is equal to 9.81 m/sec².The value of the gravitational acceleration varies according to the height and the planet.

The value of the gravitational acceleration on the earth is 9.81 m/sec².While the value of g at the moon is 1.6333 m/sec².

Hence acceleration is the rate of change of velocity. While g is the acceleration due to gravity.

A person is dragging a packing crate of mass 100 kg across a rough horizontal floor where the coefficient of kinetic friction is 0. 400. He exerts a force f sufficient to accelerate the crate forward. At what angle above horizontal should his pulling force be directed in order to achieve the maximum acceleration?.

(c) give two reasons why using light pressure as propulsion near earth's surface is impractical.

Answers

The necessary light intensity of the disk if the disk has mass 3.89 g and radius 2.40 cm is 6.483 x 10^12cd.

Calculations and Parameters:

a. Given that:

i= intensity of light m= mass of disk g= gravitational acceleration c= speed of light a= cross-sectional area of the disk

I = P/A

= Force x Speed/Area

Gravitational force, F= GM1M2/r^2

F= ma, F= mg

I= mg x c/q

That is,

i= mass x gravitational acceleration x speed/area

b.

Mass= 3.89g

Radius, r= 2.40cm

i=?

i= mg x c/a

Speed of light= 3.0 x 10^8 m/s

Area, a= /pi r^2

= 3.142 x (0.024)^2

= 3.142 x 0.000576

= 0.0018m^2.

i= 3.89 x 10 x 3.0 x 10^8/0.0018
