A vector is any quantity that has magnitude and direction. A scalar is any quantity that has magnitude but has no direction.Displacement and velocity are vectors, distamce and speed are scalars.
Answer:Density is the mass of an object divided by its volume. Density often has units of grams per cubic centimeter (g/cm3). ... You probably have an intuitive feeling for density in the materials you use often. For example, sponges are low in density; they have a low mass per unit volume.
Explanation:
Answer:
A pendulum works by converting energy back and forth, a bit like a rollercoaster ride. When the bob is highest (furthest from the ground), it has maximum stored energy (potential energy). ... So as the bob swings (oscillates) back and forth, it repeatedly switches its energy back and forth between potential and kinetic.
Answer:
Maximum height reached is given as H = 5.00 m
Explanation:
As we know that if the ball is projected at some angle with the horizontal then the range of the projectile is given by the formula
here we have
v = 40 m/s
Now we have
now for maximum height we have
Answer:
an inhibitor of angiotensin II
Explanation:
Angiotensin, specifically angiotensin II binds to many receptors in the body to affect several systems. It can normally increase blood pressure by constricting the blood vessels but with the introduction of an inhibitor, it wouldn't bring about an increase in blood pressure.
