Answer:
Explanation:
a ) The centre of mass of a can filled completely with any liquid of any mass lies at the center of the can or at height h /2 where h is height of the can . So centre of mass of can of mass .140 kg of height 12 cm will lie at height 6 cm . Similarly center of mass of its content will also lie at height 6 cm that is center point of the content .
Hence overall center of mass of can along with its content will lie at height 6 cm initially .
b )
After the can loses all the soda , can becomes empty . Hence its center of mass will lie at its center again .
c ) Its center of mass remains unchanged as the soda drains out completely .
d ) When soda starts draining out of the can , its lower part becomes heavier than the upper part . Hence its center of mass moves downwards . Its height is lowered . As height of soda is lowered in the can , center of mass also is lowered . It reaches its lowest point when soda in the can reaches half the height or when the can is half filled .
After that center of mass again starts rising upwards until the can is completely empty .
Answer:
hydrostatic force is 327000.00 N
Explanation:
given data
base = 4 m
height = 5 m
density of water = 1000 kg/m3
to find out
hydrostatic force
solution
we know this is a triangle so we consider here a small strip PQ whoes area da in with length x and width dy
so area will be
da = base/H × height = base/H × y
so da = x dy = base/H × y dy
and we know pressure = ρ × g × h
here h = y
hydrostatic force = pressure × area
df = (ρ × g × h) × base/H × y dy
now integrate it from 0 to 5 height
f = ρ × g 
f = ρ × g 
f = ρ × g × 4/5 × 
now put value ρ = 1000 and g = 9.81
f = ρ × g × 4/5 ×
f = 1000 × 9.81 × 4/5 × (5³/3)
force = 7848 × 41.666667
force = 327000.00 N
hydrostatic force is 327000.00 N
Answer:
A=0.80
Explanation:
a=2×100/time^2. a=2×100/15.86^2. = a=0.80
RC circuit determines the capacitor's charging rate.
- In RC (resistive and capacitive) circuits, a capacitor's time constant is the number of seconds required to charge it to 63.2% of the input voltage.
- This duration is described by a single time constant. After two time constants, the capacitor will be charged to 86.5% of the input voltage.
- The RC time constant, also referred to as tau, is the time constant (in seconds) of an RC circuit and is obtained by multiplying the circuit resistance (in ohms) by the circuit capacitance (in farads), This transient reaction time T is stated in terms of = R x C, where R is the resistor value in ohms and C is the capacitor value in farads.

The correct answer to the question is : D) Impulse
EXPLANATION:
Before going to answer this question, first we have to understand impulse.
Impulse of a body is defined as change in momentum or the product of force with time.
Mathematically impulse = F × t = m ( v - u ).
Here, v is the final velocity
u is the initial velocity
F is the force acting on the body for time t.
Hence, the perfect answer of this question is impulse m i.e the force multiplied with time is known as impulse.
