Which of the following has the highest albedo? an object that is white an object that is red an object that is black an object that is blue
Answers
Answer:
White
Explanation:
Final answer:
In terms of reflectivity or albedo, an object that is white has the highest albedo. This is because white reflects most of the sunlight that hits it, while red, black, and blue objects absorb more sunlight and have lower albedos.
Explanation:
In the context of physics, albedo is a measure of the reflectivity of an object's surface. It determines how much sunlight is reflected off the surface of an object. The scale ranges from 0 (no reflection, akin to an ideally black surface) to 1 (full reflection, similar to an ideally white surface). Among the colors mentioned, an object that is white has the highest albedo because white reflects most of the sunlight that hits it, while colors like red, black, and blue absorb more sunlight. Thus, they have lower albedo values.

In the context of Johari Window, the larger the hidden area, the:
lesser the chances of your relationships developing beyond the acquaintance level.
Explanation:
Developed by psychologists in 1955, the Johari Window is a technique largely used in self-help groups. The Window has four areas: open, blind, hidden, and unknown. From a list of adjectives, a subject selects the ones that describe himself. Then his peers also select adjectives from the list to describe the subject.
The hidden area refers to the area of the window where the adjectives selected only by the subject are placed (unlike, for instance, the open area, where adjectives chosen by the subject as well as the peers are placed). These adjectives represent qualities the subject sees in himself, but that he most likely keeps from others, since the peers are unable to see them. The larger this area, the more this person is "hiding" from others. Therefore, the lesser the chances of his relationships developing beyond the acquaintance level.

The competing market is one that consists of companies that provide products or services identical to yours. Knowing who your competitors are, what their differentials, the audience, values, strategies, products and services is critical. To do so, conducting a thorough study of the competing market will certainly help in understanding the stage your business is in, as well as in developing strategic actions.
Now, even with fierce competition, don't worry. The competing market is an indication that there is demand, meaning there is an audience interested in paying for your products or services. However, the growth of companies competing with you will influence this demand by making it less need-based, so you must work to make your product different.

Question:
For the R-C circuit shown in figure 1 on page 3, R= 100 ohms and C=1.00F.
A)What is the time constant of the R-C circuit?
B) consider that the capacitor is initially not charged and the voltage of the battery is 3.00 V. The switch is closed at t=0. Using the appropriate formulas, write down the voltage Vc(t) on the capacitor and the current I(t) in the circuit.
C) consider that the capacitor is initially fully charged to 3.00 V. The switch is open at t=0. Using the appropriate formulas, write down the voltage Vc(t) on the capacitor and current I(t) in the circuit.
- Your Question is missing the figure as well, which is attached below, please find it in the attached file.
Answer:
Part.A
100 seconds
Part.B
Vc(t)=0V
I(t)=30mA
Part.C
Vc(t)=3.0V
I(t)=0A
Explanation:
Given Data:
Resistance=R=100 ohms
Capacitance=C=100F
Part.A: Time constant=T=?
Time constant:
Time required to charge the capacitor upto 63.23% of the applied voltage is called a Time constant.
As we know that time constant for the RC (circuit having only resistor and capacitor) is equal to product of resistance and capacitance
so
Part.B: Vc(t) and I(t)=? If switch is closed
Given Data:
Voltage of the battery=Vs=3.0V
Capacitor is not charged initially and switch is closed at t=0 means that the circuit will become short (because capacitor is charging) in which current I(t) exist and voltage Vc(t) is zero.
Short circuit:
The circuit in which current is maximum and voltage is zero.
Thus voltage on the capacitor is Vc(t)=0V
Now we can find I(t) as follow:
Thus, Applying Kirchoff's Law (sum of all voltages is zero) on the circuit in the figure attached below, we get
putting values, we get
Current in the circuit is
Part.c: Vc(t) and I(t)=? if switch is opened
If switch is opened and capacitor is fully charged then the capacitor will act as a battery and will supply will voltage as it has stored the charge. The switch is open it means the circuit is open.
So current I(t) in the circuit is zero=0A
and voltage Vc(t) exist which can be found as:
Applying Kirchoff's law, we get
thus voltage on the capacitor is
