Find the force, in Newtons, on a rectangular metal plate with dimensions of 4 m by 8 m that is submerged horizontally in 9 m of

water. Water density is 1000 kg/m3 and acceleration due to gravity is 9.8 m/s2. If necessary, round your answer to the nearest Newton.

Answer:

F \approx 3*10^6

Explanation:

From the question we are told that:

Dimension of plate: 4 m by 8 m

Depth submerged d=9m

Water density \rho=1000 kg/m3

Gravity g=9.8m/s^2

Generally the equation for Volume is mathematically given by

 V=L*B*d

 V=4*8*9

 V=288

Therefore The mass of Plate is

 m=\rho*V

 m=1000*288

 m=288000kg

Generally the equation for Force on the plate is mathematically given by

F=ma

 F=288000*9.8

 F=2822400N

 F=2.8*10^6

 F \approx 3*10^6

A block of metal is 3 cm on each side. It has a mass of 283.5 grams. What is the density of the metal.
Luden [163]
Density =  \frac{Mass}{Volume}
\\\rho=\frac{m}{V}
\\\\\rho=\frac{283.5}{3^3}
\\\\\rho=\frac{283.5}{27}
\\\\\rho = 10.5  g/cm^3

1.A river flowing steadily at a rate of 240 m3/s is considered for hydroelectric power generation. It is determined that a dam c
SIZIF [17.4K]

Answer:

the power that can be generated by the river is 117.6 MW

Explanation:

Given that;

Volume flow rate of river v = 240 m³/s

Height above the lake surface a h = 50 m

Amount of power can be generated from this river water after the dam is filled = ?

Now the collected water in the dam contains potential energy which is used for the power generation,

hence, total mechanical energy is due to potential energy alone.

E_{mech} = m(gh)

first we determine the mass flow rate of the fluid m

m = p×v

where p is density ( 1000 kg/m³

so we substitute

m = 1000kg/m³ × 240 m³/s

m = 240000 kg/s

so we plug in our values into ( E_{mech} = m(gh) kJ/kg )

E_{mech} = 240000 × 9.8 × 50

E_{mech} = 117600000 W

E_{mech} = 117.6 MW

Therefore, the power that can be generated by the river is 117.6 MW
