A 20600 kg sailboat experiences an eastward force 17700 N due to the tide pushing its hullwhile the wind pushes the sails with a force of 60000 N directed toward the northwest (45◦ westward of North or 45◦ northward of West). What is the magnitude of the resultant acceleration of the sailboat?

Answers

Answer:

2.23 m/s²

Explanation:

mass of sail boat, m = 20600 kg

Force along east, F1 = 17700 N

Force along north west, F2 = 60000 N

write the forces in vector form

\overrightarrow{F_(1)}=17700 \widehat{i}

\overrightarrow{F_(2)}=60000\left ( - Cos45 \widehat{i}+Sin45\widehat{j}\right )

\overrightarrow{F_(2)}=-42426.41\widehat{i}+42426.41\widehat{j}

Net force acting on the boat

\overrightarrow{F}=\overrightarrow{F_(1)}+\overrightarrow{F_(2)}

\overrightarrow{F}=17573.6\widehat{i}+42426.41\widehat{j}

The magnitude of net force is given by

F=\sqrt{17573.6^(2)+42426.41^(2)}

F = 45922 N

Acceleration = force / mass

a = 45922 / 20600

a = 2.23 m/s²

The amount of heat neededto raise 2.0 kg of a substance by 80 K is 33 kJ. What is the specific heat of
the substance?

Answers

Q = mcθ
 
Where Q = Amount of heat in J
             m = Mass of substance in kg
              θ  = Temperature rise in °C or K
              C = Specific heat capacity in J/kgK

From given data:
Q = 33 kJ = 33 000 J, m= 2.0 kg,   θ  = 80 K,   c = ?

33000 =  2 * c * 80
33000 = 160c
160c   = 33000
       c   =  33000/160 = 206.25

Therefore specific heat capacity is 206.25 J/kgK

Suppose that at room temperature, a certain aluminum bar is 1.0000 m long. The bar gets longer when its temperature is raised. The length l of the bar obeys the following relation: l=1.0000+2.4×10−5T, where T is the number of degrees Celsius above room temperature. What is the change of the bar's length if the temperature is raised to 14.1 ∘C above room temperature?

Answers

Answer:

0.00034 m

Explanation:

Since the length of the aluminium bar, L is given by , L = 1.0000 + 2.4 × 10⁻⁵T and T = 14.1°C, we substitute the value of T into L. So, we have L = 1.0000 + 2.4 × 10⁻⁵ × 14.1°C = 1.0000 + 0.0003384 = 1.0003384 m. The change in length is thus 1.0003384 - 1.0000 = 0.0003384 m ≅ 0.00034 m
