Answer:
BaF2
Explanation:
since you got the valence numbers just do the scissors move where you:
give the F the 2 and give the Ba the 1 so it be like
BaF2 here is the chemical compound
Answer:
0.075 T
Explanation:
When a current-carrying wire is immersed in a region with magnetic field, the wire experiences a force, given by
where
I is the current in the wire
L is the length of the wire
B is the strength of the magnetic field
is the angle between the direction of I and B
In this problem we have:
L = 0.65 m is the length of the wire
I = 8.2 A is the current in the wire
F = 0.40 N is the force experienced by the wire
since the current is at right angle with the magnetic field
Solving the formula for B, we find the strength of the magnetic field:
Answer:
<h3>The answer is 61,200 m</h3>
Explanation:
To find the distance covered by the dolphin , we use the formula
<h3>distance = velocity × time</h3>
From the question
velocity = 17 m/s
time = 3600 s
We have
distance = 17 × 3600
We have the final answer as
<h3>61,200 m</h3>
Hope this helps you
A rotation motion is a motion that takes place around a fixed axis.
Like gears turning on each other.
Explanation:
There are generally two types of collisions between objects - elastic and inelastic.
Elastic collisions are those that converse kinetic energy. Inelastic are those that do not conserve kinetic energy.
In the ideal inelastic collision and elastic collisions, momentum is conserved.
Typically, ideal inelastic collisions are represented when both masses stick together after the collision.
The problem statement gives no indication that this is an ideal inelastic collision (the cars stick together) or an inelastic collision (no energy degradation expression is given). Therefore, we should assume that the cars are experiencing an elastic collision.
Since both momentum and kinetic energy are converved, we can observe that...
where v is the initial velocity and u is the final velocity (after the collision)
The problem statement gives us three of the four unknowns. So we can easily apply either equation to solve the the velocity of the 1600-kg car after the collision. Momentum is easier to work with.
