What conditions would probably exist the dew point and dry bulb temperatures to be the same at the ground ?

Physics

OLEGan [10]3 years ago
4 0

Answer: The conditions would probably exist the drew point and dry bulb temperatures to be the same at the ground because When the dew point temperature and air temperature are equal, the air is said to be saturated. Dew point temperature is NEVER GREATER than the air temperature. Therefore, if the air cools, moisture must be removed from the air and this is accomplished through condensation.

Sliva [168]

Answer:

t = 0.37 seconds

Explanation:

t = (1/4)T

Maximum acceleration is;

a_max = Aω²

In simple harmonic motion, we know that v_max = Aω

Thus, a_max = v_max•ω

ω = a_max/v_max

We know that Period is given by;

T = 2π/ω

From initially, t = (1/4)T so, T = 4t

Thus, 4t = 2π/(a_max/v_max)

t = (2π/4)(v_max/a_max)

We are given;

Maximum velocity;v_max = 1.47 m/s

Max acceleration;a_max =6.24 m/s²

Thus,

t = (2π/4)(1.47/6.24)

t = 0.37 seconds

(f) What do you mean by: (i) 1 J energy (ii) 1 W power​
max2010maxim [7]

Explanation:

Watts are defined as 1 Watt = 1 Joule per second (1W = 1 J/s)

which means that 1 kW = 1000 J/s. A Watt is the amount of energy (in Joules) that an electrical device (such as a light) is burning per second that it's running.

After a nucleus with 85 protons undergoes alpha decay, it has<br><br> ? protons.
Valentin [98]

Answer:

After a nucleus with 85 protons undergoes alpha decay, it has  83 protons.

Explanation:

In an alpha particle there are two protons

In the given substance's nucleus, there are total of 85 protons

After the decay, the proton number reduce

The current proton number after decay is

85 -2 = 83

After a nucleus with 85 protons undergoes alpha decay, it has  83 protons.

(a) A hole of 1 cm in diameter is drilled in a plate of steel at 20°C. What happens to the diameter of the hole as the steel is
Anestetic [448]

When heat is applied to a substance/material or steel in our case, a series of changes will occur, one of which is Expansion.

Hence the hole will expand from 1cm to a diameter that is greater.

Thermal expansion refers to the expansion or contraction of the dimensions of the solid, liquid or gas when their temperature is changed.

<h3>Types of Expansion</h3>
  • Linear expansion
  • Areal expansion and
  • Volumetric volume.
