The normal force is always perpendicular to the surface. So it would be straight to the left of the wall
Answer:
it probs gos fast then it was it would be easy if u asked us if their was any mass or friton
Explanation:
Answer:
The correct answer is C.
Clarify any confusing information in the instructions.
Explanation:
The very first thing that we need before conducting a scientific investigation is a set of instructions which might include the following information:
-What we are experimenting on?
-How are we going to do it?
-What things are needed for it?
If there are any confusions in the instructions, the chances of making a mistake rises. So, it is very important to clarify the confusions found in the instructions before choosing things needed for the experiment and starting the experiment.
Answer:
Explanation:
Both the pizza rolls are on two circular paths having different radii because one of them is on the rim and another is near the central axis. Their angular velocity are equal . That means they rotate by same angle in equal period of time. So in Δt they make equal angles at the centre. Hence their angular displacements are equal.
But length of arc made by them in equal interval of time that is Δt are different. Ir is so because their speed are different . Speed v and angular speed ω are related to each other as follows.
v = ω r .
So for objects in motion on circular paths having different radii , v are different even if their ω are same.
length of arc l = v Δt
So length of arc will be proportional to their v which will be proportional to r if their ω are same .
Hence length of arc will be proportional to radius of circular path, ie their distance from the centre .
Hey there!
<span>Which statement best summarizes Gregor Mendel’s contribution to science?
Mendel is considered the "father of genetics". He did NOT increse the number of peas </span>
<span>produced by a single plant using cross-breeding techniques, discover grean peas and yellow peas, or invent the green pea by cross-breeding thousands of pea plants.
This means your answer is option D.
Hope this helps
Have a great day (:
