shes 85.5 m away attempting to subdue the monkey with a tranquilizer gun. The vet knows that the moment the gun fires, the monkey will be frightened and fall down from the branch.

Answer:

3.03°

Explanation:

Given that

Height of the tree branch, h = 4.5 m

Distance of the veterinarian away, d = 85.5 m

The vet is to aim at the monkey at a particular angle. If we consider the force of gravity that will be acting on the dart. Then the angle that will be needed will be calculated as this.

So the angle is

Tan θ = opposite / adjacent

Tan θ = 4.5 m/ 85.5 m

Tan θ = 0.053, then

θ = Tan^-1 (0.053)

θ = 3.03°

Therefore, the angle needed is 3.03°

A. The substances that are formed.

B.  The substances that are changed.  

C. The starting materials.

D.  The chemical ingredients

ANSWER

The correct option is C.

A chemical reaction is made up of two distinct parts, which are reactants and products. The reactants refers to the starting material of the chemical process, which react together under suitable conditions. The products on the other hand refers to the new substance that is formed as a result of the reaction of the reactants. The reactants are usually find at the left side of chemical equations while the product is found at the right.

A scale measures the weight of a light object to be 11.000 lbs ± 0.034 lbs. what is the uncertainty if this same scale is use to
Gre4nikov [31]

The uncertainty of the heavy object if the scale remains constant is 0.24 lbs.

<h3>What is uncertainty in measurement?</h3>
  • This is the error associated in an attempt measure the object accurately.

The percent uncertainty in measuring the light weight object is calculated as follows;

= \frac{0.034}{11} \times 100\%\\\\= 0.309\%

The uncertainty of the heavy object if the scale remains constant is calculated as follows;

= \frac{0.309}{100} \times 78.0 \ lbs\\\\= 0.24 \ lbs

What is an equilibrant
professor190 [17]
The question seems to be what is an equilibrant force.

The answer is "an added force that produces equilibrium.

Here you have more insight:

<span>an object that has no net force acting on it? This object indeed is in equilibrium but the object is not the equilibran force.

the reaction force in an action-reaction pair of forces?

the reaction force is not an equilibrant force. The reaction force exists always but equilibrium is only possible if the net force is cero.

an added force that produces equilibrium? this is the right  answer.</span>
