Answer:

There would be tremendous earthquakes and tsunamis, followed by massive volcanism around the impact zone. The ozone layer would be destroyed. The oceans would turn acidic. The Sun would be blotted out, probably for decades.

Answer: Well it depends on the size. If the asteroid was the size of a basketball, it would most probably turn to dust by the time it reaches the surface. But, if it was the size of Australia, then most probably everyone would die.

A 0.40-kg mass attached to the end of a string swings in a vertical circle having a radius of 1.8 m. At an instant when the stri

Answer:

T = 8.55 N

Explanation:

When string makes an angle 40 degree with the vertical then it will have two forces on it

1) gravitational force (mg)

2) Tension force in string (T)

now we know that net force towards the center of the path is known as centripetal force and it is given as

$T - mg cos40 = F_c$

$T - (0.40\times 9.8)cos40 = \frac{mv^2}{L}$

$T = 3 + \frac{0.40\times 5^2}{1.8}$

$T = 3 + 5.55$

$T = 8.55 N$

A 19.0-μF capacitor and a 44.0-μF capacitor are charged by being connected across separate 45.0-V batteries.

nikitadnepr [17]

Answer:

Explanation:

C1 = 19 micro farad

C2 = 44 micro farad

V = 45 V

The relation between the charge and the potential is

q = C x V

where, c is the capacitance and V be the potential difference

q1 = C1 x V = 19 x 45 = 855 micro Coulomb

q2 = C2 x V = 44 x 45 = 1980 micro Coulomb

Now the charge is shared, the charge on both the capacitors = (q1 + q2)/ 2

q = ( 855 + 1980) / 2 = 1417.5 micro Coulomb

Potentia across 44 micro farad

V' = q/C2 = 1417.5 / 44 = 32.2 V

anyanavicka [17]

To solve this problem it is necessary to apply the concepts related to work and power.

Remember that work is defined as the force applied on a body - or exerted by it - to travel a certain distance, and that the power is that energy mentioned to perform that activity in a given instance of time.

Mathematically work is defined as

$W = Fd$
