Answer:

Option A. 10¯⁶

Explanation:

To know which option is correct, we must bear in mind, the relationship between micro coulomb (μC) and coulomb (C). This is given below:

Recall:

1 μC = 10¯⁶ C

Therefore, to convert micro coulomb (μC) to coulomb (C), multiply the value given in micro coulomb (μC) by 10¯⁶.

Thus, option A gives the correct answer to the question.

stellarik [79]

Answer:

3.125 m

Explanation:

We are given that

Mass of box=m=11.2 kg

Speed of box=u=3.5m/s

Coefficient of kinetic friction= $\mu_k=0.2$

Final velocity,v=0

a.We have to find the horizontal force applied by worker to maintain the motion.

According to question

Horizontal force=F= $f=\mu_kmg$

$g=9.8m/s^2$

Substitute the values

Horizontal force= $F=0.2\times 11.2\times 9.8=21.95 N$

b.According to work-energy theorem

$W=\frac{1}{2}mv^2-\frac{1}{2}mu^2$

$-\mu mg s=\frac{1}{2}(11.2)(0)^2-\frac{1}[2}(11.20)(3.5)^2$

$-\mu mg s=-\frac{1}{2}(11.2)(3.5)^2$

$0.2\times (11.2)\times 9.8\times s=\frac{1}{2}(11.2)(3.5)^2$

$s=\frac{11.2\times (3.5)^2}{2\times 0.2\times 11.2\times 9.8}$

$s=3.125 m$

Hence, the box slide before coming to rest=3.125 m

Harman [31]

Answer:

<em>Undergo global warming at a faster rate than what we are seeing currently</em>

Explanation:

Climate can be described as the average weather of a place. The climate of a particular place can be described after looking at the temperature of the place for a year or more.

If factors, such as the Sun and volcanoes controlled climates then there would be an increase in the temperature and more global warming. Volcanoes can be described as heat erupting from mountains which will, of course, lead to global warming.

The 26-kg sphere c is released from rest when θ = 0∘ and the tension in the spring is f = 100 n

aleksandr82 [10.1K]

You are given the mass of a sphere that is 26 kg sphere and it is released from rest when θ = 0°. You are also given the force of the spring that is F = 100 N. You are asked to find the tension of the spring. Imagine that the sphere is connected to a spring. The spring exerts a tension and the spring exerts gravitational pull. This will follow the second law of newton.

T - F = ma
T = ma + F
T = 26kg (9.81m/s²) + 100 N
T = 355.06 N
