      d.  400k

plz...... answer it

Answer 1

Answer:

HI

THIS IS YOUR ANSWER

3 - decreases as we go to the centre of the earth

4 - negative

5 - both a and b ( tides and motion of moon )

6 -

given =

w = mg

mass = 40 kg

g = 9.8 m/s²

w = 40 kg * 9.8 m/s²

=392 N

Answer 2

3. The value of 'g' d) Is more at the equator and less at the pole.

• On the basis of altitude the value of g changes.

4. The ball is thrown up, the value of ‘g’ will be c) negative.

• The value of g will remain unchanged but the sign is negative since the acceleration is against the motion.

5. The gravitational force causes d) Both a and b.

• The gravitational force of the moon causes high tides and low tides
• The Earth's gravity keeps the Moon orbiting us.

6. Given:

     Mass = 40 kg

   To find:

     Weight

  Solution:

     Weight = mass * gravitational acceleration

                  = 40 x 9.8

                  = 392 N

Hence, the weight is 392N.
