I am 11 year old and u just needed to login in so I can't answer ur questions
If the same atoms appear on both sides, then it's balanced.
In this reaction, there are 4 Oxygens, 2 Carbons, and 2 Nitrogens on each side. So numerically, <em>it's balanced</em>. But I don't know enough chemistry to say whether the reaction is possible.
Answer:
The speed of transverse waves in this string is 519.61 m/s.
Explanation:
Given that,
Mass per unit length = 5.00 g/m
Tension = 1350 N
We need to calculate the speed of transverse waves in this string
Using formula of speed of the transverse waves

Where,
= mass per unit length
T = tension
Put the value into the formula


Hence, The speed of transverse waves in this string is 519.61 m/s.
Answer:
The work done by gravity is 784 J.
Explanation:
Given:
Mass of the block is, 
Height to which it is raised is, 
Acceleration due to gravity is, 
Now, work done by gravity is equal to the product of force of gravity and the distance moved in the direction of gravity. So,

Force of gravity is given as the product of mass and acceleration due to gravity.
. Now,

Therefore, the work done by gravity is 784 J.
Answer:
13 blocks
Explanation:
The total distance the student travels is 13 blocks.
Distance is the length of path covered during the motion of a body.
To find distance:
Total distance = Number of blocks to the west + number of blocks to the north + number of blocks to the east
Total distance = 3blocks + 4blocks + 6blocks = 13blocks
