Answer:
Elements are made up of only one type of atom. Each element has a unique chemical symbol. Elements can be identified by their atomic number.
To solve this problem we will proceed to use Newton's second law for which the mass (m) multiplied by the acceleration (a) is defined as the Force (F) applied on a body, mathematically that is,
According to the statement for the first object, the acceleration is,
For the second object the acceleration is,
Solving for the mass of the second object,
Therefore the correct answer is D.
Answer:
The charge on point A is = 2.4 × C
The charge on point B is = 1.2 × C
Explanation:
Given data
Distance (r) = 0.19 m
Magnitude of the charge on A is twice that of the charge on B i.e.
F = 46 N
We know that force between the charges is given by
= 1.2 × C
= 2 ×
= 2 × 1.2 ×
= 2.4 × C
Therefore the charge on point A is = 2.4 × C
The charge on point B is = 1.2 × C
Explanation:
1) speed of bicycle =
speed of bicycle=
speed of bicycle = 10 miles/hour
2)speed of rocket =
speed of rocket=
speed of rocket= 742.57 meter/second
3)speed of jet plane =
speed of jet plane=
speed of jet plane= 132 meter/second
4)speed =
time =
time of trip=
time of trip = 4.375 hour
5) Distance = speed × time
Distance = 6 × 3 × 60
Distance = 1080 meter
6) Average speed =
Average speed =
Average speed = 81.6 km/hour
7) Time =
Time =
Time = 3750 m/s
