The answer is to remove 4 electrons.
Answer with Explanation:
We are given that
Mass of box=35 kg
Coefficient of static friction between box and truck bed=0.202
Acceleration due to gravity=
a.We have to find the force by which the box accelerates forward.
Force by which box accelerates=
Force by which box accelerates=
b.We have to find the maximum acceleration can the truck have before the box slides.
Force =friction force
Hence, the truck can have maximum acceleration before the box slide=
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

B. Purchase a small plastic container and mark 1-ounce increments on the outside to determine volume. Pour 5 ounces of water into the container, and place in the freezer for 8 hours. Compare the frozen or ending volume with the liquid or beginning volume.
<h3>How much water expands when frozen?</h3>
Ice is less denser than the liquid form. Water is the only known non-metallic substance that expands when it freezes because it is the unique property of water. Water density decreases and it expands approximately about 9% by volume. For calculating the expansion of water, plastic container is the best option. We know that water expands when the water freezes because it is a unique property of water which allows the survival of aquatic organisms.
So we can conclude that option B is the right answer.

Answer:
The resistance is found to be 6Ω
The current is found to be 0.66 A
Explanation:
The resistance of a conductor in terms of its dimensions is given as:
R = ρL/A
where,
R = resistance = ?
ρ = resistivity = 3 x 10⁴ Ω.m
L = Length = 4 mm = 0.004 m
A = Cross-sectional area = 0.2 mm² = 0.2 x 10⁻⁶ m²
Therefore,
R = (3 x 10⁴ Ω.m)(0.004 m)/(0.2 x 10⁻⁶ m²)
<u>R = 6 Ω</u>
Now, the potential difference between both ends of the resistor is:
ΔV = 16 V - 12 V = 4 V
Now, from Ohm's Law:
V = IR
I = V/R
I = 4 V/ 6 Ω
<u>I = 0.66 A</u>
