The impulse exerted by a force F on an object in a time
is given by
In our problem, we have a force of 120 N: F=120 N, applied to the baseball for a time of
. Therefore the impulse is
Answer:
B. Identifying the types of data to be gathered
Explanation:
Identifying the types of data to be gathered is one of the part of designing a set of experimental procedure.
An experimental procedure is a methodical process that must be followed in order to attain the goal of the experiment.
- As with most experiments, data is collected for further analysis and interpretation.
- The choice of way of collecting data and the type of data to be collected is very important when designing an experiment.
Answer:
8.3 x 10⁻⁷ C
Explanation:
Electric flux will enter the face at x=0 and exit at face x= 25 m
On the other faces , field lines are parallel so no flux will enter or exit .
Flux entering the face at x = 0
= electric field x face area
= 560 x 25 x 25 = 350000 weber
Flux exiting the face at x = 25
= 410 x 25 x25
= 256250 weber
Net flux exiting from cube ( closed face )
350000 - 256250 = 93750 web
Apply gauss'es theorem
Q / ε = Flux coming out
Q is charge inside the closed cube
Q / ε = 93750
Q = 8.85 x 10⁻¹² x 93750
= 8.3 x 10⁻⁷ C
