Answer:The rod touching your hand will have a Negative charge.
Explanation: This phenomenon is described as charging by induction,the other iron rod became charged as a result the repulsion force existing between the positively charged iron rod and the electronic forces around the election sphere. This make it different from the charging done by contact where both iron rods have close contact and electron transfer is achieved through contact. The shows that an electric charge can be persuaded and caused to transfer to another metallic particle without physical contact with the charged metallic particle.
Answer:
The initial neutral rod would be induced with negative charges.
Explanation:
This process is called charging by induction. When you bring the charged rod close to that of the neutral, the charges in it would be redistributed. The positively charged rod attracts the negative charges within the neutral rod and repel like charges. Touching the neutral with hand causes the positive charge to be neutralised due to earthing. Thus the neutral rod has now been charged negatively.
b. 11 kg.
c. 110 kg.
d. 1100 kg.
e. none of the above
A lamb that weighs 110 N has a mass of around 11 kg. Hence, option B is correct except B all options are incorrect.
The mass of a physical body is a measure of its entire makeup. Inertia, or the body's resistance to acceleration when a net force is applied, is also measured by this term. The strength of a body's gravitational pull on other bodies is also influenced by its mass. The kilogram is the fundamental mass unit of the SI.
In physics and engineering, the weight of an object refers to the gravitational force that pulls on it. Weight is the term used in many widely used textbooks to describe the gravitational force acting on the object. Some people think of weight as a scalar quantity that gauges the gravitational force's strength.
According to the question, the given values are :
Weight, w = 110 N and,
Taking value of g = 10 m/s²
As we know that :
w = m × g
110 = m (10)
m = 11 kg
Hence, the mass of the lamb will be 11 kg.

Answer:
b) 67.5 N
Explanation:
Force (F) = mass (m) × acceleration (a)
The mass (m) is 45 kg, and the acceleration (a) is 1.5 m/s². Plug these values into the formula:
F = 45 kg × 1.5 m/s²
F = 67.5 N
So, the force created by the person is 67.5 Newtons.
b. the perfect cosmological principle
c. the oscillating universe theory
d. the steady state theory
Answer: b. the perfect cosmological principle
Explanation:
The perfect cosmological principle is the extension of the cosmological principle. It states that the universe is homogeneous. It looks same from everywhere. It will look the same. It will never change over time instead of some of the gross changes occurring in the universe.
