Answer:
(a) increase by times
Explanation:
Natural frequency of a wave in a string is given by:
where, L is the length of the string, T is the tension in the string and is the linear density of the string.
Considering the length and linear density of the string are constant, if the tension in a string is doubled, the natural frequency of the string would:
Thus, the natural frequency of the string would increase by times.
Answer:
attracted
Explanation:
Electrons are negative.
A positively charged object will attract a negatively charged object
Answer:
3859 g
Explanation:
1 pound = 0.454 kg
therefore, 8.50 ponds = 0.454*8.50 = 3.859
to covert kilograms into grams you need to multiply it by 1000
=3.859*1000
= 3859 grams
A pure substance that cannot be decomposed by ordinary chemical change. . Energy can be converted from one form to another, but it cannot be created or destroyed in ordinary chemical or physical means.
Answer:
The velocity of the seeds relative to the ground as they travel through the air is 2.6 meters per second.
Explanation:
From Physics, we know that the absolute velocity of the seeds () is the sum of the absolute velocity of the farmer () and the velocity of the seeds relative to the farmer (), all measured in meters per second. That is:
(1)
If we know that and , then the velocity of the seeds relative to the ground is:
The velocity of the seeds relative to the ground as they travel through the air is 2.6 meters per second.
