Answer:
0.125Hz
Explanation:
The relationship between period and frequency is given by
where f is the period and T is the frequency.
Given that T = 8.00s
The period of a swinging object is the time it takes to make one complete oscillation, it is measured in seconds (s) while the frequency is the number of complete oscillations made per unit time and it is measured in Hertz (Hz). Period and frequency are inverse of each other.
Answer:
19.12 m/s.
Explanation:
The following data were obtained from the question:
Final velocity (v) = 0 m/s
Breaking Acceleration (a) = – 4.57 m/s²
Distance (s) = 40 m
Initial velocity (u) =.?
The initial velocity of the car can be obtained as illustrated below:
v² = u² + 2as
0² = u² + (2 × –4.57 × 40)
0 = u² + (– 365.6)
0 = u² – 365.6
Collect like terms
u² = 0 + 365.6
u² = 365.6
Take the square root of both side
u = √365.6
u = 19.12 m/s
Therefore, the car was initially moving at 19.12 m/s.
Answer:
11.2m³
Explanation:
Applying Archimedes principle we have it that
Weight of submarine+ weight of tank+ weight of compound air =uptrust
So
(40000+2000+37V) x9.8= (30+V) 1030 x 9.8
38910= 993V
V= 11.2m³
