Answer:
B) When an electrically charged object comes close to an uncharged object, it will attract it.
Explanation:
Suppose that you rubbed a balloon with a sample of animal fur such as a wool sweater or even your own hair. The balloon would likely become charged and its charge would exert a strange influence upon other objects in its vicinity. If some small bits of paper were placed upon a table and the balloon were brought near and held above the paper bits, then the presence of the charged balloon might create a sufficient attraction for the paper bits to raise them off the table. This influence - known as an electric force - occurs even when the charged balloon is held some distance away from the paper bits. The electric force is a non-contact force. Any charged object can exert this force upon other objects - both charged and uncharged objects.
Any charged object - whether positively charged or negatively charged - will have an attractive interaction with a neutral object. Positively charged objects and neutral objects attract each other; and negatively charged objects and neutral objects attract each other.
Answer:
The mass of the cart is 26.7 kg.
Explanation:
To find this answer use the formula for acceleration first to find how fast the object had to be acccelerating to gain a velocity of 45m/s in 8 seconds flat.
Here's the formula for acceleration:
a = V- V₀ ÷ T (Wher V = final velocity; V₀ = Initial velocity, and T = time)
Plug all known values into the equation and you get -
a = (45m/s - 0m/s) ÷ 8 , which works out to 5.625 m/s²
Once you have this value then you place it into the equation for finding an object's mass, and that formula is:
M = or M =
This works out to 26.6667 kg or approx. 26.7 kg if you are asked to round it to three significant figures.
In reproducing organisms, the number of chromosomes in the body (somatic) cells typically is diploid (2n; a pair of each chromosome), twice the haploid (1n) number found in the sex cells, or gametes. The haploid number is produced during meiosis.
Answer:
Iceland’s Eyjafjallajökull Volcano
Explanation:
Iceland’s Eyjafjallajökull Volcano eruption happened on March 20, 2010. It consisted of different stages:
- The first eruption happened in an ice-free area (1660 m high), this eruption was little but it produced lava.
- The next phase of the eruption, on 14 April, produced a 2.5 km wide caldera under the ice cap. This led to the melting of such ice, flooding the southern region, 800 people were evacuated. During this phase, the interaction between magma with water created a plume of volcanic ash and gas of over 10 km. This lasted from April 15th to April 21st.
Even though the eruption itself wasn't that big, the melting ice that flooded the surrounded area and the ashes column that blocked the air paths for almost a week, converted this event into one of the most disastrous eruptions.

Answer:
Lysosomes and mitochondria are functionally connected
Explanation:
Lysosomes are required for normal mitochondria function. It has been proposed that the lysosomal vesicles provide amino acids, lipids and ions to the mitochondria, thereby these organelles are essential for mitochondrial activity
