Answer: 0.137 m
Explanation:
Given
Mass of brick, m = 3 kg
Angle of inclination, Φ = 34°
Force constant of the spring, k = 120 N/m
The force of the brick, F can be gotten using the relation
F = mg
F = 3 * 9.8
F = 29.4 N
Now, the force parallel to the incline, F(p) can be gotten using the formula,
F(p) = F sinΦ, so that
F(p) = 29.4 * sin 34
F(p) = 29.4 * 0.559
F(p) = 16.4 N
The stretch distance then is,
d = F(p) / k * 1 m
d = 16.4 / 120
d = 0.137 m
Thus, the spring stretched by a distance of 0.137 m

Havent seen this one before but the explanation should help you out :)
Explanation:
There are only three atomic bonds.
Ionic bonding.
Covalent bonding.
Metallic bonding.
Answer:23 seconds
Explanation:
Acceleration(a)=3.87m/s^2
distance(d)=1020m
Initial velocity(u)=0
d=uxt + (axt^2)/2
1020=0xt + (3.87xt^2)/2
1020=(3.87xt^2)/2
Cross multiply
1020x2=3.87xt^2
2040=3.87xt^2
t^2=2040/3.87
t^2=527.13
t=22.95
Time(t) is approximately 23seconds

Speed = Distance/time
Speed = 800/40
Speed = 20 metre per second
