Explanation:
An object that is partly or completely submerged experiences a greater pressure on its bottom surface than on its top.
Answer:
1.04x s
Explanation:
->The maximum current through the resistor is
= V/R = V/= V/R× = V/R
Voltage 'V'=50V
Effective resistance 'R'= 25.0-Ω+ 10.0 Ω= 35.0 Ω
Therefore, =50/35=> 1.43 A
->The maximum charge can be determined by
Q = CV
where,
Capacitance of the capacitor 'C' = 30.0µF = 30×10-⁶F
Therefore,
Q=30×10-⁶ x 50=>1.5 x
In order to find that when does the maximum current occur, the time taken given the quantity of charge and the electric current is:
t= Q / I=> 1.5 x / 1.43
t= 1.04x s
Answer:
the answer is unvelles pretty am I right
Answer:
i) 0.9504
ii) 0.0452
Explanation:
Given data: reliability of hydraulic brakes= 0.96
reliability of mechanical brakes = 0.99
So the probability of stopping the truck = 0.96×0.99= 0.9504
At low speed
case: A works and B does not
= 0.96×(1-0.99) = 0.0096
case2 : B works and A does not
= 0.99×(1-0.96) = 0.0396
Therefore, probality of stopping = 0.0096+0.0396 = 0.0492
Answer:
The average velocity of Samuel’s entire trip is 1.16 m/s.
Explanation:
Given:
Distance covered at first checkpoint (d₁) = 925 m
Distance covered at second checkpoint (d₂) = 673 m
Time taken for reaching first checkpoint (t₁) = 10 min = 10 × 60 = 600 s [∵1 min = 60 s]
Time taken for reaching second checkpoint (t₂) = 13 min = 13 × 60 = 780 s
Now, the average velocity of Samuel's entire trip is given by the formula:
Total distance traveled is equal to the sum of the distances traveled at first and second checkpoints. So,
Total distance covered =
Total time taken =
Therefore, the average velocity is given as:
Hence, the average velocity of Samuel’s entire trip is 1.16 m/s.
