Answer: The density of this piece of jewelry is 
Explanation:
To calculate the density, we use the equation:
Mass of piece of jewellery = 130.8 g
Density of piece of jewellery = ?
Volume of piece of jewellery =( 62.4-47.7 ) ml = 14.7 ml = 
Putting values in above equation, we get:
Thus density of this piece of jewelry is
Answer:
m = 95000 kg
Explanation:
Given that,
Net force acting on the house, F = 2850 N
Initial speed, u = 0
Final speed, v = 15 cm/s = 0.15 m/s
We need to find the mass of the house. Let the mass be m. We know that the net force is given by :
F = ma
Where
a is the acceleration of the house.
So,
So, the mass of the house is equal to 95000 kg.
Repetitive Transcranial Magnetic Stimulation (TMS) is the procedure that is being performed on Tommy, while he is awake.
What is Transcranial Magnetic Stimulation?
Transcranial magnetic stimulation (TMS) is a non-invasive method for mood control. It does not require the patient to be sedated and is usually performed on completely conscious patients.
- In this procedure, the nerve cells are stimulated by magnetic pulses by placing electromagnetic coils against the scalp of the patient. The patient is then stimulated repetitively which is why it is known as repetitive TMS.
- Repetitive TMS can be targeted to specific sites of the brain in contrast to other brain stimulation therapies which are more generalized. Magnetic pulse activates the regions of the brain that show decreased activity during conditions like depression.
Tommy sings during the procedure because the region of the brain responsible for memory and singing is stimulated by this procedure.

Answer A, climbing vines. Thigmotropism is growth in response to mechanical contact.
Explanation:
Filtration is used to separate mixtures containing materials of relative size differences.
They are typically used to separate solid-liquid mixtures.
- The filter system must have been used in the experiment to separate filtrates and collect them in the reaction.
- The liquid passes through the filter and leaves behind the solute or suspension in the filter.
- The fluid that passes through the filter is the filtrate.
- This is a separation technique used for most solid - liquid mixtures in which the solid is not soluble.
- An example is sand and water mixture.
