Answer:
In a series circuit, the same amount of current flows through all the components placed in it. On the other hand, in parallel circuits, the components are placed in parallel with each other due to which the circuit splits the current flow.
To solve this problem we will apply the concepts related to power as a function of the change of energy with respect to time. But we will consider the energy in the body equivalent to kinetic energy. The change in said energy will be the difference between the two velocity data given by half of the mass. We will first convert the given units into an international system like this
Initial Velocity,
Final Velocity,
Now Power is defined as the change of Energy over the time,
But Energy is equal to Kinetic Energy,
Replacing,
Therefore the correct answer is A.
Answer:
4. Sterilization
Explanation:
A reservoir refers to the breeding ground or natural habitat of micro living organisms such as bacterias, fungi, worms, etc. Thus, a reservoir hosts or harbours pathogens and usually serves as a source of infection to other living organisms.
On the other hand, a source of infection refers to a contaminated material from which a disease can be acquired by another living organism.
Pathogen refers to a disease causing organism or substance such as fungi, protozoa, bacteria, virus, etc.
Sterilization simply means to be free from all organisms either pathogenic or nonpathogenic organisms such as spores and viruses.
An autoclave can be defined as a chamber (container) designed to expose an equipment to steam i.e a moisture at high heat and pressure for a specific period of time.
Basically, an autoclave is a container or chamber that is strongly heated and as a result, it is typically used for the sterilization of various laboratory and medical equipments using steam under pressure and high temperature.
This ultimately implies that, an autoclave avails laboratory scientist and other end users the ability to disinfect or sterilize equipments by exposing them to moisture at high heat and pressure for a specific period of time.
Answer:
a = 580 m/s^2
Explanation:
Given:
- Distance for accelerated throw s_a = 70 cm
- Angle of throw Q = 30 degrees
- Distance traveled by the javelin in horizontal direction x(f) = 75 m
- Initial height of throw y(0) = 0
- Final height of the javelin y(f) = -2 m
Find:
What was the acceleration of the javelin during the throw? Assume that it has a constant acceleration.
Solution:
- Compute initial components of the velocity:
V_x,i = V*cos(30)
V_y,i = V*sin(30)
- Use second equation of motion in horizontal direction:
x(f) = x(0) + V*cos(30)*t
75 = 0 + V*cos(30)*t
t = 75 /V*cos(30)
- Use equation of motion in vertical direction:
y(f) = y(0) + V_y,i*t + 0.5*g*t^2
Subs the values:
-2 = 0 + V*sin(30)*75/V*cos(30) - 4.905*(75/Vcos(30))^2
-2 = 75*tan(30) - 4.905*(5625/V^2*cos^2(30))
V^2 = 4.905*5625 / (2 + 75*tan(30))*cos^2(30)
V^2 = 812.0633
V = 28.5 m/s
- Use the third equation of motion in the interval of the throw:
V^2 = U^2 + 2*a*s_a
28.5^2 = 2*a*0.7
a = 580 m/s^2
