Hey wats there answerssssssssssssss need it nowwwwwwww ASAP !!!!!!!
The answer is B . You begin with a purpose for the lab, then hypothesize on what you believe will happen. Next, follow the procedures. This is always the last step, Anatoly did. Reflect upon you hypothesis, did the lab support or disprove your hypothesis. Include observations you have made. Identify errors.
Answer: sac
Tunicates are sea squirts that are found in the marine water. These animals remains attached to the rocks and the sea beds. They exhibit a body shape which looks like a barrel. The barrel has two openings called as siphons. These siphon helps in the intake of the food particles and oxygen. These animals look like sac on the sea floor.
Answer:
is applied to
Explanation:
An input force is push or pull that is applied to the machine and causes work to be done on it.
Input force for every machine should be lesser than the output force. The output force is the resulting force which produces work.
The force produced by any machine is a function of the input force and the design of the machine.
Any force applied to a machine is the input force.
Explanation:
Let x and y are two unknown resistors. When they are connected in series their equivalent resistance is 15 Ω. When they are connected in parallel, their equivalent resistance is 3.3 Ω.
For series combination,
......(1)
For parallel combination,
....(2)
We need to find the resistances of these resistors. Solving equation (1) and (2) we get :
x = 0.29 and y = 14.7
Hence, the resistances of these resistors are 0.29 ohms and 14.7 ohms.
