Venus spins the opposite direction.
Answer:
<h2>750N</h2>
Explanation:
Impulse is the change of momentum of an object when the object is acted upon by a force for an interval of time.
the expression is Ft=mv
where F= force
m= mass
t= time
v= velocity
Step one:
given data
mass m=3kg
velocity v= 25m/s
time t= 0.10seconds
Step two:
we also know that the force on impulse is given as
Ft=mv
F=3*25/0.10
F=75/0.10
F=750N
<u>The magnitude of the average force on the heavy bag if the duration of the collision is 0.1 is 750N</u>

Answer:
The correct answer is false, a plant dying after being exposed to poison is not a physical change nor is it a physical property.
Explanation:
Answer:
Explanation:
A ) 90 dB = 9 B
70 dB = 7 B
If intensity level be I₁ and I₂ respectively
I₁ / I₂ = 10⁹⁻⁷
10² = 100 times
B ) 60 dB = 6 B
If I₃ be the level of intensity of phone ring
I₁ / I₃ 10⁹⁻⁶
= 1000 times
C )
If I₄ be the intensity level of rock concert
I₄ / I₁ = 10¹¹⁻⁹
=100 times.
