Answer:

a = -10m/s²

Explanation:

Givens:

Vf = 0m/s

Vi = 50m/s

t = 5s

Use the following kinematic equation:

Vf = Vi+at

Rearrange

a = (Vf-Vi)/t

a = -10m/s²

146,000,000 Express this amount in gigadollars
Tema [17]
I saw an example of yahoo saying that 114,000,000= 0.114, so ima take a guess and say that the way in expressing 146,000,000 in gigadollars would be 0.146. I'm sorry if I am wrong. But if it is right give me a thanks so I could know if I was right or not.

What is the IEEE 802.11a center frequency in GHz, and what are its max/min data rates in Mbps? What is the IEEE 802.11b center f
kogti [31]

Explanation:

What is IEEE 802.11?

IEEE 802.11 is a set of WLAN standards for communication developed by the Institute for Electrical and Electronics Engineers (IEEE) and is unarguably most widely used WLAN technology.

Features: IEEE 802.11a

  • The operating frequency band is 5 GHz.
  • The maximum theoretical data rate is 54 Mbps, the typical throughput is around 25 Mbps and minimum data rate is 6 Mbps.
  • It can support 64 users per access point.

Features: IEEE 802.11b

  • The operating frequency band is 2.4 GHz.
  • The maximum theoretical data rate is 11 Mbps but typical throughput is around 6 Mbps and minimum data rate is 1 Mbps.
  • It can support 32 users per access point.

Wireless Coverage IEEE 802.11a Vs IEEE 802.11b:

  • Signal coverage is one of the most important factors among users.
  • The transmission range of IEEE 802.11a is not greater than 100 ft in indoor setting whereas IEEE 802.11b has a superior performance in this regard with transmission range up to 150 ft in indoor setting.
  • The data rate has a direct relation with the access point coverage area, a higher data rate means less coverage area and a lower data rate results in increased coverage.

How we can see different colors by our eyes?
IrinaVladis [17]

I DID A Science PROJECT ON THIS >:)))

basically light travels into the eye to the retina located on the back of the eye. the retina is covered withe millions of light sensitive cells called Rods and cones. when these cells detect light they send signals to the brain that help detect color.

the color of an object is determined by the wavelengths of light that it reflects. it's determined by the arrangement of electrons in the atoms of that substance that will absorb and re-emit photons of particular energies according to quantum laws.

How much charge must pass by a point in a wire in 10 s for the current inb the wire to be 0.50 a?
Ostrovityanka [42]

Charge must pass by a point in a wire is 5 Coulomb

Given:

time = 10 s = t

current = 0.50 A = I

To Find:

charge = q

Solution: Current is defined as amount of charge passing through a region per unit time. It is given by the formula

I = q/t

q = I x t = 0.50 A x 10 s = 5 Coulomb

Hence, charge must pass by a point in a wire is 5 Coulomb

A 7.30-kg bowling ball is on a storage rack that is 1.12 m above
Marina CMI [18]

Answer:

80.12J

Explanation:

Given parameters:

Mass of the bowling ball = 7.3kg

Height of the storage rack  = 1.12m

Unknown:

Energy the ball would have exerted  = ?

Solution:

To solve this problem, the potential energy is the best parameter to use.

Potential energy is the energy due to the position of a body. It is expressed as:

    Potential energy  = mass x gravity x height

So;

   Potential energy = 7.3 x 9.8 x 1.12 = 80.12J
