Gravity holds the system together
Explanation:
We have,
Length of a metal rod is 55 cm or 0.55 m
Change in length is 0.2 cm or 0.002 m
It is required to find the change in temperature of a metal rod. The coefficient of linear expansion is given by :
is the change in temperature
So, the change in temperature is 303.03 degrees Celsius.
Answer:
R = 400 ohms.
Explanation: Voltage of the battery, V = 40 V. Current in the unknown resistor I = 100mA. Let R is the resistance of the resistor. It can be calculated using Ohm's law it gives the relationship between the voltage, resistance and current.. R = V/I. R = 40 V/10-¹A. R = 400 Ohm's. So, the value of the resistance of the resistor is 400 Ohm's
Answer: Participating in all of the above can improve flexibility.
Explanation:
A practice that helps in improving or developing inherent power in order to bring peace and harmony to the body of a person is called yoga.
Yoga includes different postures that also help in providing flexibility to the body.
Pilates is another method of providing muscular strength and low impact flexibility to a human body.
Swimming also a good exercise that provides flexibility.
Thus, we can conclude that participating in all of the above can improve flexibility.
