Question

1.An object weight 10N when measured on the surface of the earth, then its
mass on the moon.
a) Increases b) Decreases c) remains same d) varies continuously

2. The frequency range of infrasonic is
a) more than 20Hz b) less than 20 Hz
c) more than 20KHz d) less than 20KHz.



​

Answer 1

b) Decrease because weight is dependent on mass and acceleration due to gravity

Answer 2

HERE COMES THE ANS:-

1:- AS WE KNOW THAT

W= mg

SO MASS DEPENDS UPON gravity ..

THERE BY GRAVITY AT MOON DECREASES 6 TIMES THAN OF EARTH ..

So wE CAN WRITE IT LIKE:-

m= w/g

THERE BY WE SEE INVERSE RELATION WITH g

AS g VALUE IS LESS SO MASS WILL BE GREATER..

2:- FREQUENCY OF INFRASONIC SOUND LESS THAN 20 HZ..

BRAINLIEST THE ANSWER PLEASE ❗☺
