Answer:
B, It reacts with oxygen to form a new substance
Explanation:
B
This shows observational learning, as Ian is following what others are doing and what others are encouraged to do. This is in contrast to other kinds of learning like classical and operant conditioning, where people learn based on associations of an event and a result (rather than based on what other people are doing).
Answer:
v
f=90km/h=25m/s
v_{_{i}}=0v
i=0
t=10\;\mathrm{s}t=10s
m=1000\;\mathrm{kg}m=1000kg
What happens to water when it becomes ice? Answer: the water level does NOT change even if it does melt, deposition is the term used when water liquid becomes solid ice, and also the water molecules DECREASE/LOWER speed and join in straight positions. 2) Answer: Conductors of both electrical and heat.
After one day, the rate of increase in Delta Cephei's brightness is;0.46
We are informed that the function has been used to model the brightness of the star known as Delta Cephei at time t, where t is expressed in days;
B(t)=4.0+3.5 sin(2πt/5.4)
Simply said, in order to determine the rate of increase, we must determine the derivative of the function that provides
B'(t)=(2π/5.4)×0.35 cos(2πt/5.4)
Currently, at t = 1, we have;
B'(1)=(2π/5.4)×0.35 cos(2π*1/5.4)
Now that the angle in the bracket is expressed in radians, we can use a radians calculator to determine its cosine, giving us the following results:
B'(1)=(2π/5.4)×0.3961
B'(1)≈0.46
