Spiral Galaxies, Irregular Galaxies and Elliptical Galaxies?
Answer:
170 N
Explanation:
The following data were obtained from the question:
Mass (m) = 20 Kg
Angle (θ) = 30°
Acceleration due to gravity (g) = 9.8 m/s²
Weight (W) =?
The perpendicular component of the weight can be obtained by using the following formula:
W = mg × Cosθ
W = 20 × 9.8 × Cos 30
W = 196 × 0.866
W = 169.7 ≈ 170 N
Therefore, perpendicular component of the weight is 170 N
Answer:
assembled
Explanation: because it was last weekend it was in the past so the past tense of assembled must be used
Answer:
This is an example of Inelastic colission
Explanation:
Step one:
given:
mass of moose m1 = 620 kg
mass of train m2= 10,000kg
Initial velocity of moose u1= 0 m/s
Initial velocity of train v1 = 10m/s
combined velocity of the system is given as v
Applying the conservation of momentum equation we have
m1u1+ m2u1= (m1+m2)V
substitutting we have
620*0+10000*10= (620+10000)V
100000= 10620V
divide both sides by 10620
V = 100000/10620
V=9.41m/s
The velocity of the moose after impact is 9.41m/s
