Answers

Answer:

calcium-47

Explanation:

Just did the test. Good Luck!

The isotopes of calcium are artificially produced to use them as a radioactive tracers. Calcium 47 is best suited for use as a radioactive tracers for body's use of calcium.

What is radioactive tracer?

A radioactive tracer consists of a chemical compound in which one or more atoms are replaced by a radioisotope.

Out of the six isotopes of calcium, calcium 47 is the most suitable isotope.

Calcium-47 consists of the half-life of about five days. This duration is long enough for biological investigations.

Thus, Calcium 47 is best suited for use as a radioactive tracers for body's use of calcium.

An ant starts at −5 m and moves 10 m left, 25 m right, 30 m left, and 5 m right. If the positive x-axis is to the right, what are the final position and total displacement of the ant?

A. position: −15 m; displacement: 70 m
B. position: 5 m; displacement: 10 m
C. position: 5 m; displacement: −70 m
D. position: −15 m; displacement: −10 m

Answers

Answer: D.

position: −15 m; displacement: −10 m

Explanation:

Displacement is the distance travelled in a specific direction.

Given that an ant starts at −5 m and moves 10 m left, 25 m right, 30 m left, and 5 m right

Total displacement = -10 + 25 - 30 + 5

Total displacement = -10

And the position = -10 -5 = -15

The correct answer is therefore D.

position: −15 m; displacement: −10 m

In a series circuit, electrons only flow along one path. Given this information, which of the following is an advantage of series circuits?
A.
The voltage is the same everywhere in a series circuit.
B.
Less resistance is produced as more devices are added to the circuit.
C.
Series circuits are simpler than parallel circuits.
D.
If one part of the circuit breaks, the other parts will still be able to operate.

Answers

Answer:

C.  Series circuits are simpler than parallel circuits.

Explanation:

In series circuit, all the components are connected in single path of current flow. If one part of the circuit breaks, the whole thing would break and none of the other parts would work. The voltage is not the same everywhere. It is different across each component. In series circuit, net resistance is more as resistance of all the components connected in series are added up. So, the only advantage of a series circuit is that is simpler than the parallel circuits.

Answers

6.

Answer:

45 meters

Explanation:

notice that is you multiply the time with the speed the units cancel to get distance.

therefore

distance=velocity(time)

distance=(3)15

distance =45 meters

7.

Answer:

1. the speed is constant

2. the average speed is .5 m/s

Explanation:

I have attached a graph of the data in excel.

from excel i got the equation of the line to be y=.5x with y being distance and x being time.

the function is a position function so if you take the derivative of it you get the velocity which is .5.

since the derivative is a constant the the speed does not change and the average velocity is the derivative.

Suppose that you, with a mass of 48kg, is standing on frictionless roller skates when someone throws you a 2.50kg mass with a velocity of 15m/s and you catch it. What will be your resultant velocity?

Answers

Answer:

v = 0.74 m / s

Explanation:

We can solve this exercise using the conservation of the moment

initial instant. Before the crash

       p₀ = m v

where m is 2.50 kg and its velocity v₀ = 15 m / s

final moment. After catching the dough

      [tex]p_{f}[/tex] = (m + M) v

As the system is made up of the mass and the person, all the forces during the impact are internal, therefore the moment is conserved

       p₀ = p_{f}

       m v₀ = (m + M) v

       v = m / (m + M)   v₀

we calculate

     v = 2.5 / (2.5 + 48) 15

     v = 0.74 m / s

There is no friction between the card and the cup.


Inertia will keep the top cup from moving very far. Gravity will pull one cup on top of another.


The opening of the cup is so much bigger than the bottom, even though the cup moves they will both be stacked together.


Both cups are moved the same amount by the friction between them and the card.

Answer:

Explanation:

The spring scale reading that shows how much force she must exert is 1. 100N 2. 50N 3. 50N.

What is the spring scale?

A simple and affordable way to determine mass is by using spring balances. The mass is suspended from the end of the spring, and the spring's deflection as a result of the mass's downward gravitational pull is measured in relation to a scale.

The word "force" has a specific meaning in science. At this level, calling a force a push or a pull is entirely appropriate. A force is not something an object "has in it" or that it "contains."

One thing experiences a force from another. There are both living things and non-living objects in the concept of a force.

Therefore, her required force is indicated by the spring scale readings of 1. 100N, 2. 50N, and 3. 50N.
