Answer:
x = 0.0873 m
Explanation:
given,
length of clothesline = 10 m
the line sags to create an angle that is 1 degree below the horizontal on each end.
As mass is hang at the center the angle made let the deflection be 'x'
as the shirt is hang at the center distance will be equal to 5 m.
now
x = 0.0873 m
Hence, the cloth line will be x = 0.0873 m from the original length of the clothesline.
The only scalar quantity is a. 35 m
Explanation:
In physics, there are two types of quantities:
- Scalar: a scalar quantiy is a quantity having only a magnitude, so it is just a number followed by a unit. Examples of scalar quantities in physics are:
Speed
Energy
Distance
Time
- Vector: a vector quantity is quantity having both a magnitude and a direction. Examples of vector quantities in physics are:
Velocity
Force
Acceleration
Displacement
Let's now analyze each given option, to evaluate if it is a scalar or a vector:
a. 35m --> it is only a unit (no direction), so it is a scalar
b. 20 m to the right --> it has a direction, so it is a vector
c. 30 m to the North --> it has a direction, so it is a vector
So, the only correct option is a).

Answer: THIS IS THE EXACT ANSWER
Three effective techniques Ann could use to learn all the US states and their state capitals are visualization and association, creating a mnemonic device, and rhyming. She could learn some of the states and their capitals by visualizing her own experiences in or about the state. As an example of association, if Ann visited Idaho last winter to see her twin brothers, she might think “I went to Idaho to visit the boys” (sounds like Boise). By employing association, she connects her own life experience to the information she wants to remember to make recalling the information easier. To remember the capital of Washington, Ann might create a mnemonic device like “George Washington went to the Olympics” (Washington’s capital is Olympia). Mnemonic devices organize information to encode it in a way that helps with recall. To effectively use rhyming, she might remember Michigan is a northern state and use “Reindeer prancing in Lansing.” Rhyming provides a cue that helps with recall. All three of these techniques work in the encoding and retrieval stages.

Answer:
They have the same rate of motion.
Explanation:
Electromagnetic radiation is a type of energy that is commonly known as light. Generally, light travels in waves, and all electromagnetic radiation travels at the same speed, which is about 3.0 × 108 ms− 1 through a vacuum.
Capacitance = Q/V
Where Q is the charge
V is the voltage
C = 3 E -7 C / 100V = 3 E -9 F = 3nF
Capacitance is also equal to
<span>C = (Eo*A)/d
Where A is the area of the plate
d is the separation between them
Eo is the permittivity (8.85E-12 for Air)
We find d
d = (8.85E-12 *0.49)/</span> 3 E-9 = 1.4455 E -3 m
d = 1.4455 mm
