Ket [755]2 years ago
3 0

Answer:

19.6Watts

Explanation:

Given parameters:

Force applied  = 49N

Distance  = 2m

Time  = 5s

Unknown:

Power  = ?

Solution:

Power is the rate at which work is being done;

   Power  = \frac{Work done }{time}

Work done  = force x distance  = 49 x 2 = 98J

So;

      Power  = \frac{98}{5}  = 19.6Watts

Mkey [24]

Answer:

The correct option is  d isothermal

Explanation:

Step 1: Data given

An adiabatic process is a process in which no <u>heat </u>is gained or lost by the system.

A constant- volume process, also called an isochoric process is a process in which the <u>volume is held constant</u>, meaning that the work done by the system will be zero.

An Isobaric process is a thermodynamic process taking place at <u>constant pressure</u>

<u />

An isothermal process is a thermodynamic process, in which the<u> temperature of the system remains constant </u>

Step 2: This situation

The container is slowly compressed, while the temperature is kept constant.

This is  an isothermal process.

The correct option is  d isothermal

Hello beautiful souls~<br>help me with these questions ​
weqwewe [10]

Explanation:

As the number of valence electrons in boron is three, it forms compounds that are electron deficient. Such electron-deficient molecules tend to accept a pair of electrons to achieve stable electronic configuration and thus, behave as Lewis acids.

The correct answer is Graphite. The change in enthalpy of carbon in diamond to graphite form is negative. It shows that graphite should be more stable than diamond. The melting point of graphite is more than diamond which implies that it is a thermodynamically most stable allotrope of carbon.
