<u>Full question:</u>

Identify the False statement. Lava of low viscosity

a. is most often a cool-temperature lava.

b. could logically build a composite volcano.

c. has low silica content.

d. indicates an area that has high potential for explosive eruptions.

<u>Answer:</u>

is most often a cool-temperature lava is the false statement about  Lava of low viscosity

<u>Explanation:</u>

When lava begets low viscosity, it can move quite smoothly across extended lengths. This produces the perfect outpourings of lava, byways, plashes, and sprays. You can likewise notice globules of lava-filled amidst volcanic gasses that burble and rise on the facade of the lava.

And extra time, volcanoes produced from low lava viscosity are extensive and have a depthless incline certain are perceived as shield volcanoes. Anywhere a volcano provides low viscosity, runny, lava it flattens faraway from the origin producing a volcano with moderate inclines.

A particular solid is electrically charged after it is rubbed, but it is not known whether its charge is positive or negative. H
pshichka [43]

Answer:

You can determine which charge has the solid by rubbing plastic and fur, and bringing near the plastic and the solid to determine if they are repeled or attracted. If they are repeled, the solid is charged negatively and if they are attracted, the solid is charged positively.

Explanation:

In order to determine the charge of the solid (negative or positive) using a piece of plastic and fur, you have to rubb the plastic with the fur (this is charging by friction)

Negative charges are transferred from the fur to the piece of plastic, therefore the plastic is charged negatively.

Then, you have to bring near the solid and the plastic. If them are repeled, it means that the solid is charged negatively (Because similar charges are repeled)

If them are attracted, it means that the solid is charged positively (Because opposite charges are attracted)

Kabir covers by car a distance 25 km through 4 minutes and then he covers 40km through 12 minutes. Calculate his average speed.
algol13

Answer:

4.1 km/m

Explanation:

The average speed=Total distance/total time

so

Total distance=25+40=65

Total time=4+12=16

so

the average speed is 65/76=4.1 km/m

The weight of an astronaut on the moon is the same as on Earth.<br> True<br> False
Vaselesa [24]

Answer:

False

Explanation:

This is due to the gravitational pull, since the moon does not have the same force or gravity like Earth, your weight would change.

An aircraft is at a standstill. It accelerates to 140kts in 28 seconds. The aircraft weighs 28,000 lbs. How many feet of runway
stiv31 [10]

Answer:

runway use is 3307.8 feet

Explanation:

given data

velocity = 140 kts = 140 × 0.5144 m/s = 72.016 m/s

time = 28 seconds

weight = 28000 lbs

to find out

How many feet of runway was used

solution

we will use here first equation of motion for find acceleration

v = u + at     ..............1

here v is velocity given and u is initial velocity that is 0 and a is acceleration and t is time

put here value in equation 1

72.016 = 0 + a(28)

a = 2.572 m/s²

and

now apply third equation of motion

s = ut + 0.5×a×t²    .......................2

here s is distance and u is initial speed and t is time and a is acceleration

put here all value in equation 2

s = 0 + 0.5×2.572×28²  

s = 1008.24 m = 3307.8 ft

so  runway use is 3307.8 feet
