The student's conclusion shows experimental bias
Just because most of nis classmates like puffed cereal ,it is inappropriate to conclude puffed cereal is better than oats cereal
Answer:
yes
Explanation:
people still skateboard that is an easy question
Answer:
Resistance, R = 8624.18 ohms
Explanation:
It is given that,
The emf of the circuit,
Capacitance of the capacitor,
Voltage across the capacitor, V = 10 V
Time for which the wipers are to operate. The formula for the voltage across the voltage is given by :
So, the value of resistance used in the charging circuit is 8624.18 ohms. Hence, this is the required solution.
Answer:
a
t = 1.235 s
b
c
Explanation:
From the question we are told that
The initial velocity is
The take of height is
The negative sign show that the height is on the negative y-axis when the take off point is consider as the origin
Generally from the kinematic equation we have that
=>
Here g is negative given that the swimmers jump motion is against gravity
solving using quadratic formula we obtain that
t = 1.235 s
Generally the highest point is mathematically evaluated as
Here v = 0 m/s since the velocity at the highest point is 0
Generally her velocity when the feet hits the water is mathematically evaluated from kinematic equation as
The negative value of the velocity is selected because the velocity is on the negative y-axis
