A baseball bat balances 74.9 cm from one end. If an 0.560-kg glove is attached to that end, the balance point moves 25.3 cm towa

timurjin [86]

Answer:

The mass of the bat is 1.09 kg.

Explanation:

Given that,

The balance point of the glove, x = 74.9 cm

Mass of the glove, m = 0.56 kg

Center of mass of the baseball bat, C = 25.3 cm

Let M is the mass of the bat. The center of mass is given by the formula as :

$C=\dfrac{MX+mx}{M+m}$

X is 0 as it is at a end

$C=\dfrac{mx}{M+m}$

$25.3=\dfrac{0.56\times 74.9}{M+0.56}$

M = 1.09 kg

So, the mass of the bat is 1.09 kg. Hence, this is the required solution.

Three Carnot engines operate between the following temperature limits.

Kipish [7]

Answer:c>a>b

Explanation:

Given

All the engine extracts same amount of heat(Q) from High-temperature reservoir

For a) 400 and 500 K

$\eta _{engine}=1-\frac{T_L}{T_H}$

$\eta _{engine}=\frac{work\ supplied}{heat\ supplied}$

$1-\frac{400}{500}=\frac{W_a}{Q}$

$W_a=\frac{Q}{5}$

For b)500 K and 600K

$1-\frac{500}{600}=\frac{W_b}{Q}$

$W-b=\frac{Q}{6}$

For c) 400 K and 600 K

$1-\frac{400}{600}=\frac{W_c}{Q}$

$W_c=\frac{2Q}{3}$

So c will give the highest amount of work

c>a>b

A 5.00 kg crate is suspended from the end of a short vertical rope of negligible mass. An upward force F(t) is applied to the en

zhuklara [117]

Answer

F = 124 N

Explanation:

given,

mass, m = 5 Kg

time, t = 4.1 s

displacement = y(t)=(2.80 m/s)t +(0.61 m/s³)t³

velocity

$\dfrac{dy(t)}{dt}=2.80 + 1.83 t^2$

$v=2.80 + 1.83 t^2$

again differentiating to get the equation of acceleration

$\dfrac{dv}{dt}= 3.66 t$

$a= 3.66 t$

force at time t = 4.10 s

F = m a

F = 5 x 3.66 x 4.1

F = 75 N

the net force when crate is moving upward

F = Mg + Ma

F = 5 x 9.8 + 75

F = 124 N

the magnitude of force is equal to 124 N
