If an object accelerating at −1.5m/s^2 takes 1.2s to reach 5.0m/s, what was its initial speed?

Answers

-1.5 m/s^2 x 1.2 seconds = -1.8 m/s

It is a negative value which means the object slowed down. The object would have originally been going that amount more.


5.0 + 1.8 = 6.8 m/s


answer: 6.8 m/s

the net force being acted on the
free body diagram below.(look at the picture I provided)

Answers

Explanation:

Pick your direction of the perpendicular forces.

Let down be negative and up be positive.

Remember that sum of all the forces is the net force,

So for the vertical forces, we have

[tex]45 + ( - 45) = 0[/tex]

Next, pick your direction of the parallel forces.

Let right be positive and left be negative so we have

[tex]15 + ( - 45) = - 30[/tex]

So our net force is 30 N to the left

Cesium has 37 isotopes, the most of any element on the periodic table. One of Cesium's most stable isotopes undergoes beta decay to form Barium-135. Which of the following is the correct isotopic notation for the original Cesium isotope before it decayed?

Answers

Cesium has 37 isotopes. One of Cesium's most stable isotopes undergoes beta decay to form Barium-135. 135 Cs 55 is the correct isotopic notation for the original Cesium isotope before it decayed.

What is beta decay?

Beta decay is a radioactive decay in which a proton is converted into a neutron or vice versa inside the nucleus of the radioactive sample.

In beta decay, an electron is ejected which increases the atomic number.

135Cs55 ⇒135Ba56  + 0e-1

Cesium      Barium      beta particle

Thus, 135 Cs 55 is the correct isotopic notation for the original Cesium isotope before it decayed.

What is the equivalent capacitance of the three capacitors in the figure (figure 1)?

Answers

The equivalent capacitance of the combination is  [tex]\dfrac{1}{C} = \dfrac{1}{C_1}+\dfrac{1}{C_2}[/tex]  where C1 and C2 are the capacitance of both capacitors in series.

What is equivalent capacitor?

Let the capacitance of both capacitors be C1 and C2. For a series connected capacitors, same charge flows through the capacitors but different voltage flows through them.

Let Q be the amount of charge in each capacitors,

V be the voltage across each capacitors

C be the capacitance of the capacitor.

Using the formula Q = CV where V = Q/C... (1)

For the large capacitor with capacitance of the capacitor C1,

[tex]Q = C_1V_1;[/tex]

[tex]V_1 = \dfrac{Q}{C_1}...(2)[/tex]

where [tex]V_1[/tex] is the voltage across [tex]C_1,[/tex]

For the small capacitor with capacitance of the capacitor [tex]C_2[/tex],

[tex]Q = C_2V_2[/tex];

[tex]V_2 = \dfrac{Q}{C_2} ... (3)[/tex]

where [tex]V_2[/tex] is the voltage across [tex]C_2[/tex],

Total voltage V in the circuit will be;

[tex]V = V_1+V_2... (4)[/tex]

Substituting equation 1, 2 and 3 in equation 4, we have;

[tex]\dfrac{Q}{C} = \dfrac{Q}{C_1} +\dfrac{ Q}{C_2}[/tex]

[tex]\dfrac{Q}{C} = Q({\dfrac{1}{C_1}+\dfrac{1}{C_2})[/tex]

Since change Q is the same for both capacitors since they are in series, they will cancel out to finally have;

[tex]\dfrac{1}{C} = ({\dfrac{1}{C_1}+\dfrac{1}{C_2})[/tex]

This gives the equivalent capacitance of the combination.

Answers

Fluorine different from chlorine, bromine, and iodine,because it is the most electronegative and reactive element in the periodic table.

What is a periodic table ?

The periodic table is an organization of all known elements in order of increasing atomic number and repeating chemical characteristics.

They are organized in a tabular format, with a row representing an era and a column representing a group.

Elements are ordered in increasing atomic number order from left to right and top to bottom.

Elements of the same group will have the same valence electron configuration and, as a result, will have comparable chemical characteristics.

Elements in the same period, on the other hand, will have an increasing order of valence electrons. Fluorine,chlorine, bromine, and iodine are halogens.

Hence,fluorine different from chlorine, bromine, and iodine because it is the most electronegative and reactive element in the periodic table.

A 0.200-g ball hangs from a thread in a vertical electric field of 3.00 kN/C directed upward. What is the
charge on the ball if the tension in the thread is (a) zero and (b) 4.00 mN?

Answers

Use the conservation of energy:
mg = Eq
q = mg / E
= ( 0.200* 10 ^ -3 kg ) (9.8 m/s^2 ) / 3000 N /C )
= 0.653 micro C

b)
mg = T + Eq
mg - T = E q
q = T-mg / E
= ( 4 * 10 ^ -3 N ) -( 0.2*10^ -3 kg ) ( 9.8 m/s^2 ) / 3000 N /C
= 1.26 micro C
Tension in the thread is 0, when
Mg = force due to electric field
.200* 10^-3*9.8 =q*3*10^3
Therefore, q= .200*10^-3*9.8/3*10^3
Net tension =4*10^-3N
i.e. mg-qE = 4*10^-3
.200*9.8*10^-3
The ball is in equillibrium if it is under the effect of three forces that is unde the tension of the thread , the pull of gravity on the ball= w=mg= 0.2*10^-3*9.8=1.96*10^-3 N and the coulumb force having charge x which is downward if the ball is positve and upward if the ball is negative. Fc=qE =x*3000N/C.
first case
T-mg-Fc=0 => T=0
mg=Fc
1.96*10^-3=x*3000
x=6.5*10^-7 C charge
second case
T= 4.00mN=4*10^-3 N
4*10^-3 -1.96*10^-3- x*3000=0
x=6.08*10^-7C

What is the energy released per kilogram?

Generally, is simply defined as

Energy used per person per year in US = 3-5 X 10^11

The 4000 v equipotential surface is 26. 0 cm farther from a positively charged particle than the 5000 v equipotential surface

Answers

The charge on the particle when the 4000 v equipotential surface is 26. 0 cm farther from a positively charged particle than the 5000 v equipotential surface is 2.89×10⁻⁵ nC.

How to find the point charge due?

The point charge can be found using the following expression.

[tex]q=\dfrac{Vr}{K}[/tex]

Here, V is the potential of a point charge, r is the distance and K is the coulombs constant.

This equation can also be given as,

[tex]r=K\dfrac{q}{V}[/tex]

The 4000 V equipotential surface is 26.0 cm farther from a positively charged particle than the 5000 v equipotential surface. For this case, the distance at both point is,

[tex]r_1=K\dfrac{q}{V_1}\\r_2=K\dfrac{q}{V_2}[/tex]

Subtract both the distance which is equal to 26 cm.

[tex]r_1-r_2=K\dfrac{q}{V_1}-K\dfrac{q}{V_2}\\26=Kq(\dfrac{1}{V_1}-\dfrac{1}{V_2})\\26=(9\times10^9)q(\dfrac{1}{4000}-\dfrac{1}{5000})\\q=2.89\times10^{-14}\rm\; C\\q=2.89\times10^{-5}\rm\; nC[/tex]

Thus, the charge on the particle when the 4000 v equipotential surface is 26. 0 cm farther from a positively charged particle than the 5000 v equipotential surface is 2.89×10⁻⁵ nC.
