Answer: 510 in Newton’s and 115 lbs

Explanation:

Considering the definition of weigh, Lisa weighs 0.5096 N or 0.1146 pounds.

Mass is the amount of matter that a body contains, while weight is the action exerted by the force of gravity on the body. That is, weight is a measure of how much force gravity exerts on the mass of an object.

The mass of an object will always be the same, no matter where it is located. Instead, the weight of the object will vary according to the force of gravity acting on it.

Weight can be calculated as the product of mass and acceleration due to gravity:

W=m×g

In this case, you  know:

Replacing in the definition of weigh:

W=0.052 kg×9.8 m/s²

Solving:

W= 0.5096 N

1 newton equals 0.2248 pound. Then W=0.5096 N= 0.1146 Pounds

Finally, Lisa weighs 0.5096 N or 0.1146 pounds.

Mark's ball falls to the ground because there is a gravitational pull from Earth's core. There are chemicals and elements in the Earth that make this pull. Mark's ball does not stay in the air for this reason.

Hope this helps you!

Answer:

This happened because there is a gravitational pull.

Explanation:

1. The property of a conductor by virtue of which it posses the flow of electric current through it is called resistance.

2. The resistance of a conductor depends on the cross sectional area of the conductor and it's resistivity.

3.This id due to the fact that the resistance of a wire is inversely proportional to the square of its diameter.

4.Due to at high temperatures , the alloy donot oxidize. Alloy doesn't melt readily and get deformed.

The  true statement about a series circuit is: the current flow through every part of the circuit is the same. Hence, option (B) is correct.

Electrical networks and two-terminal components can be linked either serially or parallelly. The electrical network that results will have two terminals and be capable of operating in either a series or parallel topology.

It depends on your point of view whether a two-terminal "thing" is an electrical network (like resistors connected in series) or an electrical component (like a resistor). In this article, a two-terminal "thing" that participates in series/parallel networks will be referred to as a "component."

Each component connected in series travels the same "electrical path" and carries the same amount of current—equal to the network's current—through it.

Answer:

220.462 pounds exact but you can round to 220 pounds

Explanation:

Answer:

Explanation:

we can look for the final velocity of the object using the eqaution of motion as shown:

v² = u²+2gH

v is the  final velocity

u is the initial velocity = 10m/s

g is the acceleration due to gravity = 9.81m/s²

H is the height of the object = 175m

Subxtitute the given parameters inti the formula and get v:

v² = 10²+2(9.81)(175)

v² = 100+3433.5

v² = 3533.5

v = √3533.5

v = 59.44m/s

Hence the final velocity of the object is 59.44m/s

Answer:

Your answer is correct, Option B

Answer:

Q = 67.04 [J]

Explanation:

In order to solve this problem, we must use the following equation of thermal energy, which relates mass to specific heat and temperature change.

[tex]Q = m*c_{p}*(T_{2} -T_{1})[/tex]

where:

Q = thermal energy [J]

m = mass = 0.5 [kg]

Cp = specific heat = 4,190 [J/kg°C]

T2 = final temperature = 65 [C]

T1 = initial temperature = 30 [C]

Now replacing:

Q = 0.5*4.190*(65 - 30)

Q = 67.04 [J]

a) density = 93.6g/12cm³

= 7.8g/cm³

b) The reason is alloying

Explanation:

volume of the rectangular block = l× b × h

= (4 × 2 × 1.5)cm

= 12 cm³

density = mass/ volume

mass = 93.6g

volume = 12cm³

therefore,

density = 93.6g/12cm³

= 7.8g/cm³

b) °Steel is formed when alloying Iron with carbon.

°Alloying improves the physical properties of the metals and non-metals

Answer:

0.04544 J

Explanation:

KE= 1/2 the mass times V squared

KE=1/2(0.142) * (0.8)^2

KE= 0.071 * 0.64

KE=0.04544

Explanation:

Given that,

The density of water is 1 g/cm³

The density of ethanol is 0.8 g/cm³

We need to find the volume of the ethanol that has the same mass as 100 cm³ of water.

Density=mass/volume

For water,

[tex]d=\dfrac{m}{V}\\\\m=dV\\\\m=1\ g/cm^3\times 100\ cm^3\\\\m=100\ g[/tex]

For ethanol,

[tex]d=\dfrac{m}{V}\\\\V=\dfrac{m}{d}\\\\V=\dfrac{100\ g}{0.8\ g/cm^3}\\\\V=125\ cm^3[/tex]

Hence, 125 cm³ of ethanol has the same mass as 100 cm³ of water.

Answer:

The net force is 10 [N] acting to the left

Explanation:

To solve this type of problem we must make a sum of the forces acting on the cart, since the forces are vectors, we know that vectors can be added, In this way forces that go in the same direction are added and forces in opposite directions are subtracted.

FL = force to the left = - 15 [N]

FR = force to the right = 5 [N]

FT = Resultant force [N]

- 15 + 5 = FT

FT = - 10 [N]

The negative sign tells us that the force acts to the left.
