Answer:The net force on the block is zero.
Explanation:
Given
Block is being pulled upward along an inclined surface at a constant speed
As speed is constant and moved in a straight line along the plane therefore its velocity is also constant .
and change in velocity is equal to acceleration therefore acceleration is zero here i.e. net force is zero acting on the body.
i would say, are sour and corrode metals
Answer:
To determine the volume of a given beaker/calorimeter by measuring its internal diameter and depth with vernier calipers. A vernier caliper is a measuring instrument with two scales: a main scale and a vernier scale that slides over the main scale.
Explanation:
if spring constant is doubled, the mass on spring will be doubled as well. according to this formula, F=ke
k stands for spring constant and e stands for the length extended
Answer:
2500m
Explanation:
given,
initial velocity(u) = 5m/s
final velocity (v) = 0 m/s ( as he/she stopped riding after 1000 secs)
time = 1000 secs
distance(s)=?
now,
s=( u+v ) ×t /2
=(5+0)×1000/2
=2500 m
hence, he /she travels 2500m far
