In a science lab, there is the adequate availability of raw materials for experiments such as chemicals while outside a science lab there isn't.
In a science lab, the availability of apparatuses and sources of heat is higher than outside a science lab.
<h3>What is science laboratory?</h3>
The science lab is a place where the experiments related to the science background are performed with the use of apparatus.
The science lab has plenty of equipment to perform the experiment whether related to physics or chemistry or biology.
Thus, source of heat and availability of raw material and equipment are the differences between the science activities carried out in a science laboratory and those carried out side of science laboratory.

#SPJ2
The angle(s) that it will reflect will be at any angle between -90° and 90. The correct answer between all the choices given is the fourth choice or letter D. Lmk if this is correct
We know, Impulse of a body is change in momentum.
Also, the final velocity of wood block is 0 m/s.
So, Impulse = Final Momentum - Initial Momentum
Impulse = 0 - ( 0.05 kg × 350 m/s )
Impulse = - 17.5 kg m/s
Therefore, the impulse exerted by the wood on the bullet is -17.5 kg m/s .
Answer:
h = 0.0259 m
Explanation:
given,
diameter of the cone = 0.0208 m
radius,r = 0.0104 m
angle of inclination,θ = 18°
initial angular velocity, ω_i = 56 rad/s
final angular velocity ,ω_f = 0 rad/s
height, h = ?
Rotational kinetic energy
Moment of inertia of coin
so,
Transnational Kinetic energy
v = r ω
now,
using conservation energy
Kinetic energy of the coin is converted into the potential energy
KE_r + KE_t = PE
h = 0.0259 m
Vertical height gain by the coin is equal to 0.0259 m
Answer:
2.5 m/s
