Answer:
Sound waves are longitudinal waves
Explanation:
Sound waves are the longitudinal waves. In longitudinal waves, the particles of the wave move parallel to the direction of propagation of waves.
It moves in the form of compression and rarefaction. When the particles are compact in a space the compression occurs while when they far apart form each other rarefaction occurs.
Answer:
12.32 m/s
Explanation:
Using the formula of maximum height of a projectile,
H = u²sin²Ф/2g................... Equation 1
Where H = maximum height, u = initial velocity, Ф = angle of projection, g = acceleration due to gravity
make u the subject of the equation
u = √(2Hg/sin²Ф)............ Equation 2
Given: H = 2.3 m, Ф = 33°, g = 9.8 m/s²
Substitute into equation 2
u = √[(2×2.3×9.8)/sin²33°]
u =√ [45.08/(0.545)²]
u = 45.08/0.297
u = √(151.785)
u = 12.32 m/s
Answer:
Reorder the steps so that step 4 appears before step 3
Explanation:
In a nuclear power plant, we have;
1) Nuclear reaction between the radio active species and the particles takes place to generate energy in the nucleus of atoms
2) The nuclear energy in the atom is converted into radiant energy, which is the energy found in light, and thermal (heat) energy
3) The produced radiant and thermal energy is released as heat and light
4) With the produced heat, steam is generated
5) The generated steam turns the steam turbines and produced mechanical energy
6) The produced mechanical energy is then converted into electrical energy in the electrical generator of the power plant
To correct Savion's error, Step 4) the light and heat should be released before step 3) the released heat can be used to generate steam, we therefore reorder the steps so that step 4 appears before step 3.
The formula that links voltage (V), resistance (R) and current intensity (I) is
Solve this formula for I to get
Plug your values for V and R and you'll get the current.
<span>Stainless steel is a metal alloy
that made up mainly of carbon and chromium. In combination
with low carbon contents, chromium is highly reactive element that imparts
remarkable resistance to corrosion and heat.</span>
Moreover, stainless
steel is mixed up with sufficient nickel, which is an essential allying element
in the series of stainless steel grades. Other components are manganese,
molybdenum, silicon, titanium, aluminum, niobium, copper, nitrogen, and sulfur.
