Janice has just measured the density of an object. Which value is possible? (Density: D = )
Sunny_sXe [5.5K]

By definition, the density of an object is given by:

D = \frac{M}{V}

Where,

M: mass of the object

V: volume of the object

Since the mass and volume of an object are numerical values greater than zero, then it follows that:

D> 0

It is important to respect the units of each measure.

For this case we can use the grams for the mass and cubic centimeters for the volume.

Answer:

A possible value for density is given by:

6 \frac{g}{cm^3}

Juliette sets the initial velocity to +10 m/s, the acceleration to zero, and clicks “start.” How can Shakina describe the subseq
ICE Princess25 [194]

Explanation :

It is given that :

The initial velocity of the car is 10 m/s.

Juliette sets the acceleration to zero.

We know that, acceleration a=\frac{v-u}{t}\

where,

u is the initial velocity and v is the final velocity.

So, final velocity will become 10 m/s.

Hence, the car will move with the constant velocity i.e. 10 m/s.

So, Shakina described that the car will move with the constant velocity of 10 m/s as acceleration is zero.

How do I solve this arithmetic sequence?
Serjik [45]

Answer:

The 16ᵗʰ term of this sequence is 82

Step-by-step explanation:

Here,

First Term = a₁ = 9

Common Difference = (d) = 2

Now, For 16ᵗʰ term, n = 16

<em>aₙ = a + (n - 1)d</em>

a₁₆ = 7 + (16 - 1) × 2

a₁₆ = 7 + 15 × 5

a₁₆ = 7 + 75

a₁₆ = 82

Thus, The 16ᵗʰ term of this sequence is 82
