Answer:
1.29 m
Explanation:
Net force acting on the dog, will be given by
where m is mass and g is acceleration due to gravity
Since the work done by the net force against the ground equals the final potential energy
Height which the dog can jump,
H=0.6+0.44=1.04 m
Total height to reach=Height to jump+ half height of the dog
=1.04 m+0.5(0.5 m)=1.29 m
Answer:
Yes
Explanation:
The cart will definitely behave differently because more weight is added to it.
In order to successfully push a cart, the applied force must exceed the force of the weight of the cart along with its constituents and the frictional force between the tyres and the floor.
<em>When more weights are added (the 2 packs of water bottles), it means that more force would be needed to overcome the opposing forces to the movement of the cart in order to successfully push the cart again.</em>
Answer:
An inherited trait are features of an organism that can be passed down to one's offspring, for example eye color, hair color shape of the nose etc. They can be passed from generation to the next generation
Answer:
Why does the Moon have so many craters compared to the Earth? Unlike the Earth, the Moon has no atmosphere to protect itself from impacting bodies. It also has very little geologic activity (like volcanoes) or weathering (from wind or rain) so craters remain intact from billions of years.
