The statement ‘An advantage of
electron microscopes compared to light microscopes is that electron microscopes
are inexpensive and commonly used in most biology laboratories allow you to view living cells, while light microscopes
do not have higher resolution that allows you to view smaller specimens allow
you to view the true colors of the specimens being viewed’ is true. In fact,
electron microscope is more efficient than a light microscope due to its
mechanism using only light without magnifying the specimen a thousand times.
Answer:
a) No
b) No
Explanation:
When a bat is hit in a game of baseball such that it flies out of the field that means it is going with some angle to the horizontal.
a)
Then is such a case the velocity of the ball is never parallel to the acceleration because there acts a net acceleration which is resultant of the acceleration due to the applied force and the acceleration due to gravity but a component of the velocity when the ball descends the height acts parallel to the gravity.
b)
At no point during the motion of the ball its velocity is perpendicular to its acceleration because it has an initial angle of projection form the horizontal.
Answer:
<em>Timing Belts </em>are components of internal combustion engines sinchronizing the handles and cranks rotation with the camshaft when operating its valves.
Internal combustion systems such as the ones found in cars for example, need a method to get the heat away from the system; the mechanical device set for that purpose is the <em>water pump</em>, which pushes coolant over the radiator, the hoses and engine block; that <em>water pump </em>is generally joint with the crankshaft pulley through those <em>timing belts</em>.
