Running on sand requires 1.6 times more energy spent than running on hard surface, so the force applied by our foot on sand is less.
Answer:
Explanation:
Thinking about the logics it can but it may be dim because 1.12 is lower than 2,5v so this will mean u lamp may not work or may work very dimely due to the low voltage it is receiving.
Answer:
C. A baseball bat strikes a baseball.
Explanation:
Newton's second law of motion states that acceleration happens when force is applied on the mass.
<em>A baseball bat strikes a baseball is the best example of Newton's second law of motion because acceleration of the baseball is directly proportional to the force by which baseball bat hit it.</em>
Hence, the correct option is 'C. A baseball bat strikes a baseball.'
Explanation:
It is given that,
An electric dipole consists of charges +2e and -2e separated by 0.82 nm
Charge, 
Distance between charges, 
Electric field strength, 
(a) The magnitude of the torque on the dipole is given by :

When dipole moment is parallel to the electric field, 


(b) When the dipole is perpendicular to the electric field, 

(Since, p = q × d)


(c) When the dipole moment is anti parallel to the electric field, 

Since, 

Hence, this is the required solution.
