Answer:
C) 5ML^2
Explanation:
2 Spheres of mass M
Bug's mass 3M
Rod length 2L, radius L
Find Rotational Inertia I
I=Σmr^2
I=(3M+M+M)L^2
I=5ML^2
Answer:
Explanation:
Acceleration is the rate of change of an object with respect to time. It is the change in velocity over the time.
The car starts at 10 meters per second and increases to 20 meters per second in 2.5 seconds.
- = 20 m/s
- = 10 m/s
- t= 2.5 s
Substitute the values into the formula.
Solve the numerator.
Divide.
The acceleration of the car is <u>4 meters per second squared.</u>
Answer:
A) Motion-sensor activated cameras
Explanation:
Motion sensor activated cameras are the ones which actuate a trigger when any sort of motion is detected by them. They can play alarming sound, send e-mails and zoom the frame of motion as a response to the detected motion.
Motion sensor cameras can be of two types:
1. Fixed view camera
2. Rotating view camera
Fixed view cameras are in fixed position and they always point in the same direction for the view while the rotating cameras are the ones which can change their direction of view.
For a small and high security space we can use the fixed type camera so that we do not miss any suspicious movements. For wide areas and distant vision we use rotating cameras.
Answer:
West
Explanation:
This is because the first caar has more mass
Energy is destroyed because animals are higher levels do not need as much energy. That is option B.
<h3>Energy movement in a food chain</h3>
Food chain is defined as the sequence that shows the feeding relationship between different organisms and how energy flows from the producers to decomposers.
The producers which are the plants traps in energy from the sunlight with the help of their green pigment called the chlorophyll.
The energy continuously flows from the producers to consumers and then to the decomposers.
From the law of conservation of energy, it is neither created nor destroyed.
Therefore energy is destroyed because animals at higher levels do not need as much energy, is not a valid statement.
