velocity is given as
when the object reached to its turning its velocity will be zero
so it will reach its turning at two time instant
Part b)
For acceleration we know that
now at t = 2
also at t=5
<u>Answer:</u>
The path followed = sun to sky to balloon to eyes
<u>Explanation :</u>
The sun gives light which reaches the sky i.e atmosphere of the earth and gets scattered , after scattering the light from the sky touches the balloon and thus coming from various directions after scattering, it touches the balloon at various points and gets reflected and then reaches our eyes and thus makes the hot air balloon visible to us.
Hence,this is the path followed by the light in order for us to see the brightly colored hot air balloon in a sunny sky and it's individual colors.
Answer:
5m/s²
Explanation:
Given parameters:
Mass of wagon = 10kg
Force of pull = 70N
Frictional force = 20N
Unknown:
Acceleration of the wagon = ?
Solution:
Frictional force is a force that opposes motion.
The net force is given as:
Net force = mass x acceleration
Force of pull - Frictional force = mass x acceleration
Insert the parameters and solve;
70 - 20 = 10 x acceleration
50 = 10 x acceleration
Acceleration = 5m/s²
Answer:
Microwaves are a type of wave that are sandwiched between radio waves and infrared radiation on the electromagnetic spectrum. In the case of microwave ovens, the commonly used wave frequency is roughly 2,450 megahertz.
