Answer:
3.14 m/s
Explanation:
We are given that
Mass of object=1.1 Kg
Spring constant=160 N/m
a.We have to find the amount by which the spring is stretched from its unstrained length(it means x)
We know that F=kx ,
b.When an object is pulled straight down by an additional distance 0.26 m and released from rest.
x=0.26 m
We have to find the speed with which the object passes through its original position on the way up.
(Law of conservation of energy)
Substitute the values then we get
Hence, the speed of an object with which the object passes through its original position on the way up=3.14 m/s
Given:
m = 70 kg, mass
F = 650 N, force
t = 0.8 s, time
Calculate the acceleration.
a = F/m = (650 N)/(70 kg)
= 9.2857 m/s²
Because the initial velocity is zero, the final velocity (after time 0.8 s) is
v = a*t = (9.2857 m/s²)*(0.8 s)
= 7.43 m/s
Answer: 7.43 m/s (nearest hundredth)
Answer: D) The convective zone
Explanation: The Sun's convective zone rapidly mixes plasma within the Sun due primarily to heat transfer by convection. Convection is also the main mode of heat transfer within a pot of boiling water. So boiling water could be used to model the convective zone.
