Carry out the following calculation. Express your answer in the correct number of significant figures.

77julia77 [94]

Answer:

43.1 g

Explanation:

Density, d is defined as the mass per unit volume of an object. Density is therefore expressed as

d=m/v

Here, m is mass and v is the volume

Making mass the subject of the formula

Mass, m=dv

The volume, v is given by

V=lwh

Substituting lwh for v in the equation for mass then mass, m=dlwh

Substituting 2.6 g/cm3 for d, 4.0 cm for l, 1.8 m for w and 2.3 for h then the mass of the block will be

M=2.6*4*1.8*2.3=43.056 g

Expressing it in 1 decimal place, mass is approximately 43.1 g

The electric field in a region is uniform (constant in space) and given by E-( 148.0 1 -110.03)N/C. An additional charge 10.4 nC

enyata [817]

Answer:

The y-component of the electric force on this charge is $F_y = -1.144\times 10^{-6}\ N.$

Explanation:

<u>Given:</u>

Electric field in the region, $\vec E = (148.0\ \hat i-110.0\ \hat j)\ N/C.$
Charge placed into the region, $q = 10.4\ nC = 10.4\times 10^{-9}\ C.$

where, $\hat i,\ \hat j$ are the unit vectors along the positive x and y axes respectively.

The electric field at a point is defined as the electrostatic force experienced per unit positive test charge, placed at that point, such that,

$\vec E = \dfrac{\vec F}{q}\\\therefore \vec F = q\vec E\\=(10.4\times 10^{-9})\times (148.0\ \hat i-110.0\ \hat j)\\=(1.539\times 10^{-6}\ \hat i-1.144\times 10^{-6}\ \hat j)\ N.$

Thus, the y-component of the electric force on this charge is $F_y = -1.144\times 10^{-6}\ N.$

Fill in the chart below to identify the name of the process that explains the state of change indicated, the states of matter be

yuradex [85]

1. Changing from solid to a liquid is called melting / fusion and happen

at the melting/ fusion point.

Reason: melting point is a temperature at which a solid melt and converts into liquid by providing heat.

2. Changing from liquid to gas is called evaporation/boiling and happens at the evaporation/boiling point.

Reason. Evaporation is a process in which molecules from surface of liquid convert into gas.

3. Changing from a gas to a liquid is called condensation and happens at the condensation point.

Reason : In condensation process gas particles converts into liquid droplets.

4. Changing from liquid to a solid is called freezing and happens at the freezing point.

Reason : Freezing is a process that convert liquid into soilid state by decreasing temperature of that specific liquid,

The density of dry air at room temperature and atmospheric pressure Is 1.2 kg m-3. What volume would 6 kg of dry air occupy unde

larisa [96]

Answer:

V = 5 m³

Explanation:

The density of air, d = 1.2 kg/m³

Mass of the dry air, m = 6 kg

We need to find the volume o the gas. We know that, the density of an object is given by mass divided by its volume. So,

$d=\dfrac{m}{V}\\\\V=\dfrac{m}{d}\\\\V=\dfrac{6}{1.2}\\\\V=5\ m^3$

So, the volume of the dry air is 5 m³.
