The bases of developing convective cumulus clouds will be relatively higher at a location with a relatively ______ difference be

tween the surface temperature and surface dew point temperature.
Physics
1 answer:
Artist 52 [7]3 years ago
5 0

Answer:

large

Explanation:

Cumulus clouds is a term in metrology that defines the type of clouds which are characterized by its low altitude, puffy appearance, and fair-weather nature. They are generally considered as low-level clouds, with less than than 2,000m in altitude except they are the more vertical cumulus congestus form.

Thus, it can be noted that, the difference between the surface dew point temperature and the surface temperature is related to relative humidity. Hence, in a situation when there is a LARGE difference between the surface temperature and the surface dewpoint temperature, then the relative humidity is very low (e.g., 10%).

Therefore, the bases of developing convective cumulus clouds will be relatively higher at a location with a relatively LARGE difference between the surface temperature and surface dew point temperature.

If the designers of submarines do not appropriately account for hydrostatic pressure,
andre [41]

Answer:

A) the pressure could crush the submarine

Explanation:

  • The submarines are mainly used for defense purposes.
  • In world war 1 and 2 the submarines played a vital role in the war.
  • The submarines work according to the principle of buoyancy.
  • According to this principle, when seawater is filled inside the tank in a required amount, the submarines sink.
  • When the seawater is expelled, the submarine rises to above the sea.
  • Most of the time, it dives deep into the sea, the hydrostatic pressure should be taken into account.
  • If the hydrostatic pressure is not considered, the pressure could crush the submarine.

2) A skier stands at rest and begins to ski downhill with an acceleration of 3.0 m/s² {downhill). What is
Finger [1]

Answer:

337.5m

Explanation:

<u>Kinematics</u>

Under constant acceleration, the kinematic equation holds:

s=\frac{1}{2}at^2+v_ot+s_o, where "s" is the position at time "t", "a" is the constant acceleration, "v_o" is the initial velocity, and s_o is the initial position.

<u>Defining Displacement</u>

Displacement is the difference in positions: s-s_o or \Delta s
s=\frac{1}{2}at^2+v_ot+s_o

s-s_o=\frac{1}{2}at^2+v_ot

\Delta s=\frac{1}{2}at^2+v_ot

<u>Using known information</u>

Given that the initial velocity is zero ("skier stands at rest"), and zero times anything is zero, and zero plus anything remains unchanged, the equation simplifies further to the following:

\Delta s=\frac{1}{2}at^2+v_ot

\Delta s=\frac{1}{2}at^2+(0)*t

\Delta s=\frac{1}{2}at^2+0

\Delta s=\frac{1}{2}at^2

So, to find the displacement after 15 seconds, with a constant acceleration of 3.0 m/s², substitute the known values, and simplify:

\Delta s=\frac{1}{2}at^2

\Delta s=\frac{1}{2}(3.0[\frac{m}{s^2}])(15.0[s])^2

\Delta s=337.5[m]

A car of mass 940.0 kg accelerates away from an intersection on a horizontal road. When the car speed is 42.5 km/hr (11.8 m/s),
MAVERICK [17]

Answer:

0.39 m/s^2

Explanation:

Parameters given:

Mass of car, m = 940 kg

Speed of car, v = 11.8 m/s

Power supplied by engine, P = 4300 W

To get the acceleration, we must define the relationship between Power and velocity.

Power, P, is given in terms of velocity, v, as:

P = F * v

where F = force

This is because Power is given as:

P = \frac{E}{t} \\\\\\P = \frac{F*d}{t} \\\\\\=> P = F * v

(where E = energy. t = time taken, d = distance moved)

Force, F, is given as:

F = m*a

Therefore, Power will be:

P = m * a * v

Acceleration, a, will then be:

a = \frac{P}{m*v}

a = \frac{4300}{940 * 118} \\\\\\a = 0.39 m/s^2

The acceleration of the car at that time is 0.39 m/s^2

sammy [17]

Answer: you are the person in charge of building a nuclear power plant in Florida. your first choice is to select a site for building the power plant.

Explanation: To find the answer, we need to know more about the nuclear power plants and the criteria to select the site for power plant.

<h3>What you mean by nuclear power plants?</h3>
  • Nuclear power can be defined from the nuclear fission reaction.
  • These power plants will heat the water to produce steam and this steam is used to spin large turbines and thus generates electricity.
<h3>How to select the site for nuclear power plant?</h3>
  • We have to consider the following things,
  • keep distance from populated area.
  • distance from load center.
  • Accessibility to site.
  • Water availability and fuel availability.
  • waste disposal.

Thus, we can conclude that, before building a nuclear power plant, our first choice should be to select a site.
