Answer:
A
Explanation:
But global warming will have additional, far-reaching effects on the planet. Warming modifies rainfall patterns, amplifies coastal erosion, lengthens the growing season in some regions, melts ice caps and glaciers, and alters the ranges of some infectious diseases.
More force and 50 grams of water
Answer:
a=0
∑Fx = 0
Explanation:
Known data
m =1.7 kg : jeep's mass
θ = 12° :angle of the slope with respect to the horizontal direction
g = 9.8 m/s² : acceleration due to gravity
Newton's second law:
∑F = m*a Formula (1)
∑F : algebraic sum of the forces in Newton (N)
m : mass s (kg)
a : acceleration (m/s²)
We define the x-axis in the direction parallel to the movement of the block on the ramp and the y-axis in the direction perpendicular to it.
Calculated of the W
W= m*g
W= 1.7 kg* 9.8 m/s² = 16.66 N
x-y weight components
Wx= Wsin θ= 16.66*sin 12° = 3.45 N
Wy= Wcos θ =16.66*cos 12° = 16.3 N
a) Because the toy jeep lowers the ramp at a constant speed, then, its acceleration is equal to zero.
a=0
b)We apply the formula (1) to calculated ΣFx
∑Fx = m*a , a=0
∑Fx = 0
