Answer:
(d) 0.07 m/s
Explanation:
Given Data
Snowball mass m₁=0.15 kg
Ice skater mass m₂=65.0 kg
Snowball velocity v₁=32.0 m/s
To find
Velocity of Skater v₂=?
Solution
From law of conservation of momentum

So Option d is correct one
Answer:
A- 18
Explanation:
It wont let me explain how
A visual display of data or information is called a graph. There are many types of graphs. These can include pie graphs, bar graphs, and many more. Graphs are useful, because they show you visually data which is helpful to many. Hope this helped
400m in 32sec: (400/32)>12.5meters per second>
(12.5)(60)(60)(1/1000)=45km per hour
Constant speed would mean that the two forces are equivalent
Answer:
The corresponding magnetic field is
Explanation:
From the question we are told that
The electric field amplitude is 
Generally the magnetic field amplitude is mathematically represented as

Where c is the speed of light with a constant value

So


Since 1 T is equivalent to
