A simple pendulum is used to determine the acceleration due to gravity at the surface of a planet. The pendulum has a length of

SVEN [57.7K]

Answer:

Acceleration due to gravity is 20 $m/sec^2$

So option (E) will be correct answer

Explanation:

We have given length of the pendulum l = 2 m

Time period of the pendulum T = 2 sec

We have to find acceleration due to gravity g

We know that time period of pendulum is given by

$T=2\pi \sqrt{\frac{l}{g}}$

$2=2\times 3.14 \sqrt{\frac{2}{g}}$

$0.3184= \sqrt{\frac{2}{g}}$

Squaring both side

$0.1014= {\frac{2}{g}}$

$g=19.71=20m/sec^2$

So acceleration due to gravity is 20 $m/sec^2$

So option (E) will be correct answer.

Which of the following is NOT true of all the inner planets?

Artist 52 [7]

Hi there! :)

$\large\boxed{\text{B. They are called gas giants.}}$

In the solar system, we can categorize the planets as such:

Inner planets: Mercury, Venus, Earth, Mars

Outer planets: Jupiter, Saturn, Uranus, Neptune

The Inner planets are the only planets that consist of solid rock. They also do not have rings and have impact craters due to their early formation.

In comparison, all of the outer planets are primarily made up of gaseous material and contain rings.

Therefore, the correct choice is B.

1)If I'm on an elevator that breaks loose and plummets down the shaft, can I avoid harm by jumping at the last second?

umka2103 [35]

Answer and Explanation:

1) If you were to jump at the last second, you would decrease the impact velocity by 7 mph. This is because most humans have a maximum jump velocity of 7 mph. You may still get hurt, but the damage would be significantly less than if you were to not jump.

2) Bathroom mats are made of fabrics, and fabrics absorb the moisture in the air. If you were to take a shower at any temperature, the fabric will soak up the moisture in the air, so when you touch it, it doesn't feel cold.

The tile floor, however, isn't able to store the moisture into itself. The temperature of the tile will be less than the temperature of your feet.
