While riding in a hot air balloon, which is steadily descending at a speed of 1.01 m/s, you accidentally drop your cell phone?
mote1985 [20]

While riding in a hot air balloon, which is steadily at a speed of 1.01 m/s, and your phone accidentally falls.

<span>(a)    </span>The speed of your phone after 4 s is:

V= u + at

V= 1.01 + (9.8)(4)

V= 40.21 m/s

<span>(b)   </span>The balloon is ____ far:

V = u + at

V= 1.01 + (9.8)(1)

V=10.81 –distance at 1 one second

V= u + at

V= 1.01 + (9.8)(2)

V= 20.61-distance at 2 seconds

V= u+ at

V= 30.41- distance at 3 seconds

V= 40.21- distance at 4 seconds

D= 102.04 m

<span>(c)    </span>If the balloon is rising steadily at 1.01 m/s:

V= -1.1 m/s

<span> </span>

What is the amount of electric field passing through a surface called? A. Electric flux.B. Gauss’s law.C. Electricity.D. Charge
rjkz [21]

Answer:

A. Electric flux

Explanation:

Electric flux is the rate of flow of the electric field through a given area (see ). Electric flux is proportional to the number of electric field lines going through a virtual surface.

Electric flux has SI units of volt metres (V m), or, equivalently, newton metres squared per coulomb (N m2 C−1). Thus, the SI base units of electric flux are kg·m3·s−3·A−1.

A wave travelling 140 m/sec with a wavelength of 4.0 m has what frequency? _______________Meters / Hz / seconds
valentina_108 [34]

Answer:

The frequency of a wave is 35 Hz.

Explanation:

Speed of a wave is 140 m/s

Wavelength of a wave is 4 m

It is required to find the frequency. The relation between frequency, speed and the wavelength of a wave is given by :

v=f\lambda

f is frequency

f=\dfrac{v}{\lambda}\\\\f=\dfrac{140\ m/s}{4\ m}\\\\f=35\ Hz

So, the frequency of a wave is 35 Hz.
