Answer:
-5 meters
Explanation:
x = 3t² + 2t − 5
The initial displacement is when t = 0.
x = 3(0)² + 2(0) − 5
x = -5
Weight is the force applied on the planet by its mass. The weight of an object is 6 times lighter than that of the earth. Option C is correct.
What is Wight?
- It is the product of the mass and the gravitational acceleration.
- Weight is the force applied on the planet by its mass.
The formula of weight is,
Where,
- weight
- mass
- gravitational acceleration
In the question given here the gravitational acceleration of the moon is 6 times less than that of the earth.
Therefore, the weight of an object is 6 times lighter than that of the earth.

<span>77.2 k is -195.95 C
To convert from Kelvin to Celsius, you simply subtract 273.15 from the temperature. So the expression becomes
c = 77.2 - 273.15 = -195.95</span>
Answer:
B. Electrons are transferred from the fur to the plastic rod.
Explanation:
Triboelectricity or friction charging refers to the ability of materials to gain or lose electrons as a result of rubbing them against something. This phenomenon has been observed in the case of rubbing plastic rod against fur, or glass rod against silk.
In the context of rubbing plastic rod against fur, what happens is that the fur which has an excess of charges loses electrons to the plastic rod. This makes the plastic rod to become positively charged, and the fur, negatively charged.
