Answer:
A helpful mutation like camoflage would immensely help a species survive and flourish. The reason being the appliances of such a mutation. Camoflage is one of the most apllicable of abilities. It can be used as a defense mechanism, to hide in plain sight, it can be used offensively to avoid being seen while hunting and it can even be used as a form of communication between the species. All of these appliances would greatly benefit the species and would most definitely help it survive and flourish.
<h2>Hello!</h2>
Orbital motions are the result of the balance between the forward motion (its direction will be related to a reference point) of a body in space (like planets, moons) and big size (and mass) body.
The gravity pulls the small size body to the big one, as result, the speed of the small body and the gravity of the big size body creates a perfect balance, describing what we call an orbit.
The small size body is always trying to move forward while the gravity of the big size one attracts it when the balance is perfect, it creates an endless cycle (orbit)
If the balance is not perfect, for example, if the speed of the small size body is too high, the body will continue its forward movement and there will not be an orbit. On the opposite side, if the big body size is too big, the gravity will attract it completely and crash.
Have a nice day!
Answer:
r = 0.5 m
Explanation:
First we find the angular speed of the ball by using its period:
ω = θ/t
For the time period:
ω = angular speed = ?
θ = angular displacement = 2π rad
t = time period = 0.5 s
Therefore,
ω = 2π rad/0.5 s
ω = 12.56 rad/s
Now, for the radius:
v = rω
r = v/ω
where,
v = linear speed = 6.29 m/s
r = radius = ?
r = (6.29 m/s)/(12.56 rad/s)
<u>r = 0.5 m</u>
Answer:
(a). The blood travel during this acceleration is 0.0231 m.
(b). The time for the blood to reach its peak speed is 0.0459 sec.
Explanation:
Given that,
Acceleration = 22.0 m/s²
Speed = 1.01 m/s
(a). We need to calculate the distance
Using equation of motion
Where, v = final speed
u = initial speed
a = acceleration
s = distance
Put the value into the formula
(b). We need to calculate the time
Using equation of motion
Put the value into the formula
Hence, (a). The blood travel during this acceleration is 0.0231 m.
(b). The time for the blood to reach its peak speed is 0.0459 sec.
Answer:
The maximum wavelength of incident light that can produce photoelectrons from silver is 423.5 nm.
Explanation:
Given;
work function of silver, Φ = 2.93 eV = 2.93 x 1.602 x 10⁻¹⁹ J = 4.6939 x 10⁻¹⁹ J
Apply Einstein Photo electric effect;
E = K.E + Ф
Where;
E is the energy of the incident light
K.E is the kinetic of electron
Ф is the work function of silver surface
For the incident light to have maximum wavelength, the kinetic energy of the electron will be zero.
E = Ф
hf = Ф
where;
c is speed of light = 3 x 10⁸ m/s
h is Planck's constant, = 6.626 x 10⁻³⁴ J/s
λ is the wavelength of the incident light
Therefore, the maximum wavelength of incident light that can produce photoelectrons from silver is 423.5 nm.
