Answer:

a) 210 Ω

b) 21 V

c) 0.07 A, 0.03 V

d) VAE = 7 V

VEB = 14 V

VAF = 9 V

VFB = 12 V

Explanation:

a) 100 Ω and 200 Ω are in series, equivalent = 100 + 200 = 300 Ω,

300 Ω and 400 Ω are in series, equivalent = 300 + 400 = 700 Ω

300 Ω and 700Ω are in parallel, so the equivalent resistance between A and B is R where

1/300 + 1/700 = 1/R, get R = 210 Ω

b) Given I = 0.1 A

so VAB = I * R = 1 * 210 = 21.0 V

c) I₁ + I₂ = I = 0.1, so I₂ = 0.1 - I₁

I₁ * 300 = I₂ * 700

I₁ * 300 = (0.1 - I₁) * 700

get I₁ = 0.07 A, I₂ = 0.1 - I₁ = 0.03 A

d) VAE = I₁ * 100 = 7 V

VEB = I₁ * 200 = 14 V

VAF = I₂ * 300 = 9 V

VFB = I₂ * 400 = 12 V

A vessel at rest at the origin of an xy coordinate system explodes into three pieces. Just after the explosion, one piece, of ma
tresset_1 [31]

Answer:

Explanation:

a. Given that:

m- mass of first & second piece, 3m-mass of 3rd piece,\bar v_1-velocity of first piece(-23\dot i \ m/s) and \bar v_2 as velocity of 2nd piece (-23\dot j \ m/s)

Let \bar v_3 be velocity of 3rd piece=?

#Vessel is at rest before explosion. Considering conservation of linear momentum:

m\bar v_1 +m\bar v_2 +3m \bar v_3=0   #Dividing both sides by m, m\neq 0

\bar v_1+ \bar v_2 +3\bar v_3=0\\3\bar v_3=-(\bar v_1 +\bar v_2)\\\bar v_3=-\frac{1}{3}(\bar v_1 +\bar v_2)

#Plug the\bar v_1 ,\bar v_2  values:

\bar v_3=-\frac{1}{3}(-23\dot i -23\dot j)=\frac{1}{3}(23\dot i +23\dot j)

#So the magnitude of the third piece is:

|\bar v_3|=\sqrt{(23/3)^2+(23/3)^2}\\=10.84m/s

Magnitude of the 3rd piece is 10.84 m/s

b. To find direction of the magnitude (as an angle relative to the x-axis), we find \angle \theta. The angle is obtained by getting the tan inverse as:

\theta=tan^-^1(\frac{23/3}{23/3})\\=45\textdegree

-The direction of the magnitude (angle relative to the x-axis) is 45°

Putting a beaker of water in a microwave and turning it on for a minute or two will increase the temperature of the water. Descr
Jobisdone [24]

Answer:

The equipment to use is: a beaker, a fixed amount of water, a thermometer.

The mass of water, the time, the temperature for each time should be noted and a graph of Temperature versus time should be made

Explanation:

The design of an experiment is to place the beaker in the microwave, with a good amount of water (approximately ⅔ of its capacity) and turn it on for small periods of time, generally the minimum is 30 s, quickly open the microwave, place a thermometer or better yet an infrared thermometer to measure the temperature of the water; repeat this several times.

The advantage of the infrared thermometer is that it reduces the transfer of heat between the water and the thermometer.

The mass of water, the time, the temperature for each time should be noted and a graph of Temperature versus time should be made.

The equipment to use is: a beaker, a fixed amount of water, a thermometer.

The main precaution that must be taken is not to open the microwave while it is on.

A block is thrown with an initial velocity of 30.0 m/s at an angle of 25.0o above the horizontal. What is the highest elevation
Serga [27]

The highest elevation reached by the ball in its trajectory is 16.4 m.

To find the answer, we need to know about the maximum height reached in a projectile.

What's the mathematical expression of the maximum height reached in a projectile motion?

  • The maximum height= U²× sin²(θ)/g
  • U= initial velocity, θ= angle of projectile with horizontal and g= acceleration due to gravity

What's the maximum height reached by a block that is thrown with an initial velocity of 30.0 m/s at an angle of 25° above the horizontal?

  • Here, U = 30.0 m/s and θ= 25°
  • Maximum height= 30²× sin²(25)/9.8

= 16.4m

Thus, we can conclude that the highest elevation reached by the ball in its trajectory is 16.4 m.
