A block of aluminium of density 7900 kg/m3 has a volume of 250 cm. Find the<br>mass of the block.​
pashok25 [27]

Answer:

mass of block=2.7 gm

Explanation:

concept: Density=mass/volume

given:ρ=2700 kg/m^3 and v=250 cm^3 (in cm^3 not in m^3)

=> v= convert cm^3 to m^3

there fore= 1 cm^3=1 cm*1 cm*1 cm

i.e 1 cm^3=1/100*1/00*1/100 m^3 => 1 cm^3=1/1000000 m^3

ρ=m/v

=>mass=ρ*volume

=>mass=2700*1/10^-6

=>mass=2.7*10^-3 kg =>2.7 gm

a) since a=0 therefore, friction force =0

b) friction = 59.5 × 1 =59.5 N.

c)maximum acceleration = 0.566 × g =5.54 m/s².

<h3>What is Friction force?</h3>

The force preventing sliding against one another of solid surfaces, fluid layers, and material components is known as friction. There are various kinds of friction: Two solid surfaces in touch are opposed to one another's a relative lateral motion by dry friction.

<h3>What is acceleration?</h3>

Acceleration is the rate at which an object's velocity with respect to time changes. They are vector quantities. The direction of the net force acting on an object determines the direction of its acceleration.

Hence, (a) since a=0 therefore, friction force =0, (b) friction = 59.5 × 1 =59.5 N, (c)maximum acceleration = 0.566 × g =5.54 m/s².

14. The real risk-free rate of interest is 2%. Inflation is expected to be 3.5% the next 2 years and 6% during the next 3 years
Naddika [18.5K]

Answer:

3-year = 6.33%

5-year = 7%

Explanation:

Yield in security = Risk free rate + Maturity risk premium + Inflation premium + Liquidity premium + Default risk premium

Maturity risk premium is given as 0

Yield on 3-year treasury securities is 2 + [(3.5 + 3.5 + 6) / 3] + 0

= 6.33%

Yield on 5-year treasury securities is 2 + [(3.5 + 3.5 + 6 + 6 + 6) / 5] + 0

=7%
