Name an acid which is highly corrosive and should never be tested by mouth.​
Vitek1552 [10]

Answer:

We all know that HCI is highly corrosive mineral acid. It's produced naturally in our (Human being) Stomach

It (HCI) is produced by the gastric glands in stomach. HCI activates the enzyme Pepsin and creates an acidic medium which kills the bacteria which might have entered while digestion & also making it simpler for further digestion.

HCI does not harm our stomach because the gastric gland also produces Mucus which helps in preventing the damage of inner wall (layer) of stomach from the action of this Acid.

A projectile is thrown with an initial speed vo = 25.0 m/s at an initial angle with the horizontal ao = 45.0. a . Find the time
Natali [406]

Answer:

See the explanation below

Explanation:

To solve this problem we must decompose the initial speeds into x & y.

v_{o}_{x}=25*cos(45)=17.67[m/s]\\v_{o}_{y}=25*sin(45)=17.67[m/s]\\

The acceleration of  gravity is equal to g = 9.81[m/s^2] downward.

The maximum height is when the velocity of the projectile is zero in the component y, that is, it will not be able to go higher, by means of the following kinematic equation we can find that time, for that specific condition.

a)

v_{y}=(v_{y})_{0}+a*t\\0 = 17.67 - 9.81*t\\17.67 = 9.81*t\\t=1.8 [s]

Note: Acceleration is taken as negative as it is directed downwards.

b)

The position in the x component can be found using the following kinematic equation

x=(v_{x})_{o}*t\\x=17.67*1.8\\x=31.82[m]

The position in the y component can be found using the following kinematic equation

y =(v_{y})_{o}*t+\frac{1}{2} *g*t^{2} \\y=17.67*1.8-0.5*9.81*(1.8)^{2}\\ y=15.91[m]

c)

Since the motion on the X-axis is at constant speed, there is no acceleration, so the only acceleration that exists is due to gravity

d)

In the attached image we can see, the projectile with the vectors of acceleration and velocity.
