The paper clip did because it is a conductor. A pencil is made with wood and that is an insulator.
Answer:
Very easy question
For x-component, we use Fₓ = Fcosα
For y-component, we use Fy = Fsinα
The major problem is with angle α.
Here α = 90+30
Because the angle is measured from +ve X-axis.
By putting values if you know co-ratios that how Sin and cos Convert to each other then you have got it.
So for further calculation,
Fₓ = Fcos(90+30) = 25(-sin30)
Fₓ = -25(1/2) = 25/2 = 12.5 - will be eliminate because force in magnitude is not "-ve"
As it is
Fy = Fsin(90+30) = Fcos30
Fy = 25 (√3 /2) = 25√3/2

The frequency f of the AC source is determined as 0.446 Xc.
<h3>
Frequency of the AC source</h3>
The frequency of the AC source is calculated as follows;
Xc ≡ 1/2fC
where;
- Xc is the capacitive reactance
- f is frequency
- C is capacitance
fC = 2Xc
f = 2Xc / C
f = (2Xc)/4.48
f = 0.446 Xc
Thus, the frequency f of the AC source is determined as 0.446 Xc.

Gravity is the force that pulls us to the surface of the Earth, keeps the planets in orbit around the Sun and causes the formation of planets, stars and galaxies.
Answer:
See below
Explanation:
- Venus Express (2005 - 14)
- Galileo (1989 - 90): As it flew by Venus on its way to Jupiter, it collected measurements of charged particles, dust and magnetism, infrared and ultraviolet spectral observation, data for infrared lower - atmosphere maps, and 81 camera images
- Magellan (1989 - 90)
- Vega 1 (1984 - 85)
- Vega 2 (1984 - 85)
- Venera 4 (1964): Atmosphere made up of entirely carbon dioxide, found that temperatures ranged from 40 degrees Celsius high up in the atmosphere to 280 degrees Celsius closer to the surface, and pressures ranged 15 to 22 atmospheres
- Venera 6 (1969)
- Venera 7 (1970): Became first spacecraft to return data from another planet and reported surface temperature of 475 degrees Celsius and atmospheric pressure 90 times greater than Earth's
- Venera 8 (1972)
- Venera 9 (1975)
- Venera 10 (1975): Transmitted images from the surface
- Venera 11 (1978): Sent back evidence of thunder and lightning as well as presence of carbon monoxide in lower altitude
- Venera 12 (1978)
- Venera 13 (1981 - 82): Returned first color images and found out the pressure was 84 times the pressure at sea level on Earth and the temperature was 457 degrees Celsius, before succumbing to them
- Venera 14 (1981 - 82): Sent back images of Venus
- Venera 15 (1983): Created radar map of Venus with Venera 16
- Venera 16 (1983)
- Pioneer Venus 1 (1978): Radar mapped nearly the entire planet, resolving features as small as 80 kilometers
- Pioneer Venus 2 (1978): Consisted of 4 separate atmospheric probes
- Mariner 2 (1962): Flyby attempt discovered ground temperatures as high as 428 degrees Celsius, but detected no water vapor or evidence of a magnetic field around planet
- Mariner 5 (1967): During flyby, measured surface temperature of 267 degrees Celsius
- Mariner 10 (1973 - 74): Took first ultraviolet images of Venus on way to Mercury
- Akatsuki/Venus Climate Orbiter (2010 - today)
These are just some of the successful attempts by probes at or near Venus.
