A 100 kg mass is pulled along a frictionless surface by a horizontal force F such that its acceleration is 8.0 m/s2. A 20 kg mas

nadya68 [22]

Answer:

a) 60 N

b) 860 N

Explanation:

Given that,

$m_1$ = 100 kg

$m_2$ = 20 kg

$a_{1}$ = 8.0 $\frac{m}{s^{2}}$

$a_{2}$ = 3.0 $\frac{m}{s^{2}}$

a) By Newton's Law,

∑ $F_{m_2,x} = f_k = m_{2} * a_{2}$

∑ $F_{m_2,y} = F_{N} - m_{2} * g = 0$

Hence,

$f_k = m_2 * a_2 = 20 * 3 = 60 N$

b) By Newton's Law

∑ $F_{m_1,x} = F = m_{1} * a_{1}$

Hence,

$F = m_{1} * a_{1} = 100 * 8 = 800 N$

Net force acting on 100 kg mass,

$F_{net} = F + f_k = 800 + 60 = 860 N$

Hello people ~

skad [1K]

Answer:

64q

Explanation:

Note that

Charges are addaptive quantities

Here

Capacitance C and potential V is given

We know

Q=CV

So charge is also same

Now

there are 64 drops so 64q charge

The boiling point of ethanol is 78 ��

34kurt

<span>The conversion for Kelvin from Celsius is simple since the units change at same rate (degree for degree) but haven't different zero reference. The Kelvin scale represents absolute zero. The celcius scale moves degree per degree with kelvin scale but has a zero based on freezing point of water. The conversion is 273 + (temperature in celcius) = temperature on kelvin scale. Note 273 is a rounded number to nearest whole number. The actual figure is a number with decimal. 273.15 can also be used if you want more significant figures.

so 273 + 78C = 351 K </span>
