Question

Fill in the blanks so that the following statements are true. (6)
1. _________ is not an animal of the arthropod group. (Ginga, Butterfly, Leech) 2. If an object moves at a constant speed of 10 m s-1 on a circular path with radius r, then the object moves _________. (Constant velocity, acceleration, constant acceleration)
3. When force is applied to an object, its _________ is not affected. (mass, shape, velocity).
4. The initial velocity of a free falling object is ________.(More, 9.8 m s-1 , zero)
5. Sound waves cannot propagate from _________. (Glass, water, vacuum)
6. Tuberculosis is a disease caused by _________. (Viruses, parasites, bacteria)​

Answer 1

1-leech
2-constant velocity
3-mass
4-zero
5-vacuum
6-viruses

Answer 2

Answer:

1) leech

2) acceleration

3)mass

4) zero

5) vacuum

6) bacteria

Explanation:

1) leech belongs to phylum annelida not to arthropoda.

2) in circular motion there is always an associated acceleration.

3) shape and velocity are changeable factors when force is applied to an object

4) when an object merely dropped from an elevated height , then initial velocity is zero

5) Sound waves need medium to progagate ,cannot progagate in vacuum

6) tuberculosis caused by Microbacterium tuberculosis bacteria.
