A boat has a mass of 4040 kg. Its engines generate a drive force of 4660 N due west, while the wind exerts a force of 880 N due

maxonik [38]

Answer:

Explanation:

Given:

Mass of the boat, m = 4040 kg

The driving force of engine, FB = 4660 N in west = + 4660 N

The force of wind, Fwi = 880 N in east = -880 N

The force of water, Fwa = 1400 N in east = -1400N

Total three forces are acting on the boat

Fnet= Fb+fwi+Fwa

Fnet= 4660 - 880 - 1400

Fnet= +2380N

Acceleration (a) = Force/mass

= 2380/4040

= 0.59m/s2

A charge of 90 C passes through a wire in 1 hour 15 minutes . what is the current in the wire

timurjin [86]

We calculate current from the formula:
$I= \frac{q}{t}$ , where q is a electric charge transferred over time t
Time should be converted to seconds:
1h 15 min= 75min= 4500s
I= $\frac{90C}{4500s}=0,02A$ Result is in unit-Ampere

The energy required to dislodge electrons from cesium metal via the photoelectric effect is 207 kJ/mol . What wavelength (in nm)

ki77a [65]

Answer:

So wavelength in nm will be $\lambda =0.956\times 10^{-19}nm$

Explanation:

We have given that the energy = 207 KJ/mol $=207\times 10^3j/mol$

Speed of light $c=3\times 10^8m/sec$

Plank's constant $h=6.6\times 10^{-34}J-s$

According to plank's rule energy of the photon is given by

$E=\frac{hc}{\lambda }$

$207\times 10^3=\frac{6.6\times 10^{-34}\times 3\times 10^8}{\lambda }$

$\lambda =0.956\times 10^{-28}m$

So wavelength in nm will be $\lambda =0.956\times 10^{-19}nm$
