Answer:dew is formed on grass
Explanation:Dew forms when the object, such as the glass, cools down to the dew point temperature. Water molecules in the air continually bombard surfaces, like blades of grass. ... If the object gets cold enough, and there is enough moisture in the air, condensation is much greater than evaporation and the film grows into dew drops.
Answer:
On removal to the glass rod the leaves of the electroscope will disperse away under the influence of the positive charge due to deficiency of electrons.
Explanation:
When a glass rod is rubbed against a nylon then the electrons from the surface of the glass rod get transferred to the nylon piece and as a result the glass rod attains positive electrostatic charge.
When this positively charged rod is brought close to the knob of an electroscope then the electrons from that metallic of the electroscope feel attraction and move toward the glass rod get concentrated on the knob.
- In this situation when any of our body part comes in direct contact to the knob these static concentrated charges get a path to flow from high concentration to a lower concentration under the influence of the electrostatic force of the rod.
- So these charges flow into our body from the knob.
- Our body acts as a reservoir for the charges on the metallic knob.
- Now after the electrons form the knob are transferred to the person's body the electroscope becomes electron deficient and hence positively charged.
- So now, on removal to the glass rod the leaves of the electroscope will disperse away under the influence of the positive charge.
Let k be the spring constant. Then you have
188=k*21.8
k=188/21.8=8.62,
In the second part you use
m g= k x
x=m g/k= 38/8.62=4.4cm
4.4 cm is the answer
Answer:... The transferred energy causes the resistor to heat up. You can feel this directly if you touch a cellphone charger when you are charging a cell ... The heat energy is enough to cause the filament to glow white-hot which produces light.
Explanation:
The answer is d because that’s the lowest velocity and it’s a straight line showing it’s not going faster
